Question

A car passes a landmark on a highway traveling at a constant rate of

55
kilometers per hour. One hour later, a second car passes the same landmark traveling in the same direction at
63
kilometers per hour. How much time after the second car passes the landmark will it overtake the first car?

Answer 1

let t be the distance for the second car to catch the first car where thefirst car is 55 km ahead
distance = speed * time
63t = 55t + 55
63t - 55t = 55
8t = 55
t = 55/8
t = 6.88 hrs or 6 hrs 53min
