Question 931755: A moving van leaves a house traveling at an average rate of 40 mi/h. The family leaves the house in a car an hour later. Following the same route as the moving van, the car travels at an average rate of 60 mi/h. How long will it take the car to catch up with the van? Answer by TimothyLamb(4379) (Show Source):
You can put this solution on YOUR website! distance traveled by van when car leaves:
s = d/t
d = st
d = 40*1
d = 40 miles
---
speed of car relative to van:
60 - 40 = 20 mph
---
time car catches van:
t = d/s
t = 40 miles / 20 mph
t = 2 hours
