Question 24943: I'm having difficulty figuring out the equation for this word problem from our variable equation unit:
A truck leaves a rest stop traveling at a steady rate of 56 mph. A car leaves the same rest stop 1/4 hour later, following the truck at a steady rate of 64mph. How long after the truck leaves the rest stop, will the car overtake the truck? Thank you!

You can put this solution on YOUR website!
First your can simplify 1/4 - 0.25h
Truck's peed = 56mph
Cars' speed = 64mph
After 1/4 hour later with the truck = 56(x+0.25)
In where x is the distance.
Car's distance = 64x

56(x+0.25)=64x
56x+14=64x
simplify
8x=14

x=1.75

hence it will take the truck 1.75hour to cross the car
