A cyclist leaves Las Vegas riding at the rate of 18 mph.
One hour later, a car leaves Las Vegas going 45 mph in the same direction.
How long will it take the car to overtake the cyclist?
:
Let t = travel time of the car
then
(t+1) = travel time of the bike
:
When car catches bike they will have traveled the same distance
A simple distance equation
:
45t = 18(t+1)
