Question

Rohan completes one round of a running track in 8 minutes and Saroj completes
it in 6 minutes. How long will it take for both to arrive at their starting point
together, if they start at the same time and maintain their speed?

Answer 1

Answer:

Given the first train completes one round of a circular track in 120 seconds and the second train does so in 180 seconds.

Now both trains move in the opposite direction in order to find time after which they will meet for the first time we need to take LCM(120,180)

120=23×3×5180=22×32×5

∴LCM(120,180)=360seconds=60360=6min

∴ the two trains meet for the first time after 6 mins from where they started.
