You can put this solution on YOUR website! A car traveling at 56 mi/h overtakes a cyclist who, riding at 16 mi/h, has a 2-hour head start.
How far from the starting point does the car overtake the cyclist.
:
First find out how long it takes for the car to overtake the cycle
Let t = travel time of the car
then
(t + 2) = travel time of the cylce
:
When this occurs, they will both have traveled the same distance
Write a distance equation; dist = speed * time
56t = 16(t+2)
56t = 16t + 32
56t - 16t = 32
40t = 32
t = 32/40
t = .8 hrs for the car to overtake the cycle
find the distance
56 * .8 = 44.8 mi
:
Confirm the dist using the cycle
16 * 2.8 = 44.8 mi
