Question

Chennai express left hyderabad for chennai at 14 : 30 hours, travelling at a speed of 60 kmph and charminar express left hyderabad for chennai on the same day at 16 : 30 hours, travelling at a speed of 80 kmph. how far away from hyderabad will the two trains meet?

Answer 1

Hey.

Here is the answer.

Let the trains meet at a distance of x km from Hyderabad.

time taken by Chennai express = x/60 hr

time taken by Charminar express = x/80 hr

As, Charminar express leaves 16:30 -14:30 =02:00 hr after Chennai express.

So, x/60 - x/80 = 2 hr

or, (4x -3x)/240 = 2

or, x = 2×240 km = 480 km


So, the trains meet at a distance of 480 km from Hyderabad.

Thanks.
