Question

..........real number class 10th ​

Answer 1

Hii buddy!

Here, first find time taken by each cyclist........

1st time = 360/48 = 7.5 hrs

2nd time = 360/60 = 6 hrs

3rd time = 360/72 = 5 hrs.

So take L. C. M. of the above time to get answer..

L. C. M. = 15.

So after 15 hrs they meet again.
