Question

A truck leaves a depot at 11 A.M. and travels at a speed of 54 mph. At noon, a van leaves the same place and travels the same route at a speed of 64 mph. At what time does the van overtake the truck?

Answer 1

let the time form 11:00 to the time of overtaking be t hrs
distance gone by the truck = 54t
distance gone by the van = 64(t-1)
but they went the same distance, so ...

54t = 64(t-1)

solve for t, and add it to 11:00

Answer 2

2:10 is the answer our teacher taught us that
