A train leaves the station and travels north at 85 km/hr and four hours later a second train leaves on a parallel track and travels north at 125 km/hr and how far from the station will they meet?
***
let x=travel time of 2nd train
x+4=travel time of 1st train
distance=speed*travel time (same for both trains)
85(x+4)=125x
85x+340=125x
40x=340
x=8.5 hrs
125*8.5=1062.5
how far from the station will they meet? 1062.5 km
