S c 20.
A boat traveled upstream 90 miles. Expert GMAT solution which accompanies this blog post. We see this questions often in GMAT tutoring sessions so went ahead. Supercharge your GMAT practice test with the 1 Chrome extension for GMAT test-takers.
A boat traveled upstream a distance of 90 miles at an average speed of v-3 miles per hour and then traveled the same distance downstream at an average speed of v3 miles per hour. If the trip upstream took a half hour longer than the trip downstream then how many hours did it take the boat to travel downstream. GMAT Tutor in NYC Online.
A boat traveled 90 miles upstream at a constant speed and then traveled the same distance downstream at a constant speed. The constant velocity of the water is 3 miles per hour. The whole trip took 125 hours.
Upstream trip took hour many more hours than the downstream trip. Let the speed on the boat be v kmh 90v-3 90v3. A boat traveled upstream a distance of 90 miles.
Tue Nov 12 2013 1055 pm. A boat traveled upstream a distance of 90 miles at an average speed of v-3 miles per hour and then traveled the same distance downstream at an average speed of v3 miles per hour. A boat traveled upstream a distance of 90 miles at an average speed of v-3 miles per hour and then traveled the same distance downstream at an average of v3 miles per hour.
If the trip upstream took half an hour longer than the trip downstream how many hours did it take the boat. By shahab03 Thu Sep 11 2008 359 am. A boat traveled upstream a distance of 90 miles at an average speed of V-3 miles per hour and then travelled the same distance downstream at an average speed of V3 miles per hourIf the trip upstream half an hour longer than downstream how many hours did it take the boat to travel.
A boat traveled upstream a distance of 90 miles at an average speed of v - 3 miles per hour and then traveled the same distance downstream at an average speed of v 3miles per hour. If the trip upstream took half an hour longer than the trip downstream how many hours did it. A boat traveled upstream a distance of 90 miles at an average speed of v-3 mph and then traveled the same distance downstream at an average speed of v3 mph.
If the upstream took half an hr longer than the trip downstream how many hours did the. A boat traveled upstream a distance of 90 miles at an average speed of. V-3 miles per hour and then traveled the same distance downstream at an.
Average speed of v3 miles per hour. If the trip upstream took half an. Hour longer than the trip.
Keeping in mind that the distance upstream as well as downstream is the same 90 miles lets say the boat has a speed rate of b thus when the boat was going upstream it really wasnt going b fast it was going b - 8 because the 8mph speed of the current is subtracting from it. A boat traveled upstream a distance of 90 miles at an average speed of v-3 mph and then traveled the same distance downstream at an average speed of v3 mph. If the trip upstream totaled 12hr longer than the trip downstream how many hours did it take the boat to travel downstream.
A boat traveled upstream a distance of 90 miles at an average speed of v-3 miles per hour and then traveled the same distance downstream at an average speed of v3 miles per hour. It the trip upstream took half an hour longer than the trip downstream how. Write a distance equation for each trip.
Dist time effective speed. 6 sc 120. 15 s-c 120.
Simplify both these equations divide the 1st by 6. Divide the 2nd by 15 results. S c 20.
S - c 8. ————–adding these equations eliminate c find s. S 14 mph speed in still water.
A boat takes 90 minutes less to travel 36 miles downstream than to travel the same distance upstream. If the speed of the boat in still water is 10 mph the speed of the stream is. Distance travel upstream Distance travels downstream 180 Let t be the time travels downstream Let t 12 travels upstream Distance Rate x time Therefore.
Distance travels upstream v-3t 12 vt 12v-3t-32. The speed of boat in still water is 12 miles per hour and speed of current is 9 miles per hour. As boat travelled 210 miles downstream in 10 hours its speed is 2101021 miles per hour.
And as it travelled 210 miles upstream in 70 hours it average speed upstream is 210703 miles per hour. Use formula drt where ddistance travelled and rspeed and t time. Let x speed of current.
Drt 18- x 5 905x Eq 1. Drt 18x 3543x Eq 2. As per statements above distance upstream distance diwnstream so d of Eq 1 d of Eq 2.
2 A boat traveled upstream a distance of 90 miles at an average speed of v-3 miles per hour and then traveled the same distance downstream at an average speed of v3 miles per hour. If the trip upstream took half an hour longer than the trip downstream how many hours did it take the boat to travel downstream. Llewyn takes 45 minutes to drive his boat upstream from the dock to his favorite fishing spot.
It takes him 30 minutes to drive the boat back downstream to the dock. The boats speed going downstream is four miles per hour faster than its speed going upstream. Heres an Official GMAT question on which we also use the T method to organize the information.
A boat traveled upstream a distance of 90 miles at an average speed of v-3 miles per hour and then traveled the same distance downstream at an average speed of v3 miles per hour. A 3 B 4 C 5 D 6 E 7 答案 C 例题 3 A boat traveled upstream a distance of 90 miles at an average speed of v - 3 miles per hour and then traveled the same distance downstream at an average speed of v 3 miles per hour.
