Question 758775
a freight train leaves a station and travels north at 55 mph. One hour later, a passenger train leaves on a parallel track and travels north at 60 mph. How long will it take the passenger train to overtake the freight train? How far from the station will they meet?
***
let x=travel time of freight train
x-1=travel time of passenger train
distance=travel time*speed
55x=60(x-1)
55x=60x-60
5x=60
x=12
x-1=11
distance=12*55=660
How long will it take the passenger train to overtake the freight train? 11 hrs
How far from the station will they meet? 660 miles
