Question 336979: You and a friend each drive 50.0 km. You travel at 83.0 km/h; your friend travels at 92.0 km/h. How long will your friend wait for you at the end of the trip? Answer by mananth(16946) (Show Source):
You can put this solution on YOUR website!
Time = Distance / speed
time taken by me = 50km
speed = 83 km/h
time = 50/83 hours = 0.60 hours
..
Friend 's speed = 92km/h
time = 50 /92
= 0.54 hours.
Time he has to wait = 0.6 - 0.54
=0.06 hours
= 0.06 * 60 = 3.6 minutes
