a car traveling 64 miles per hour passes a bus traveling 53 mph in the same direction on the highway, if they maintain their speeds, how long will it take them to be 17.5 miles apart
Answered by Reiny
So the distance between them is changing at 64-53 or 11 mph
time for that distance to reach 17.5 miles
= 17.5/11 hrs
= 1.59 hrs or appr 1 hour and 35 minutes.
