A passenger train's speed is 60 m

Question

A passenger train's speed is 60 mi/h, and a freight train's speed is 40 mi/h. The passenger train travels the Same distance in 1.5 h less time than the freight train. How long does each train take to make the trip?

Answer 1

Hi, Tom

So you need to find out how long they take to go the same distance.

 

Distance = rate x time

 

Passenger train distance = 60t 

Freight train distance = 40t

 

60(t- 1.5) = 40(t)

 

60t - 90 = 40t

20t = 90

t = 4.5 hour

So the freight train takes 4.5 hours and the passenger train takes (4.5 - 1.5) = 3 hours
