ANSWER:
let the speed of the express train be x kn/h
we know that speed= dist/time
so,
time taken by the expres train=240/x hrs
the speed of the other train= x-12 km/h
so time taken by the other train to cover the same distance=240/(x-12) hr
ATQ,
time taken by the other train = time taken by exp train +1
I actually was able to do this much.What i wanted to know was how to do the next steps to get the answer
