Answer 2

Answer: Both will be stop at the bus stop again after 75 minutes.

Explanation:

Since we have given that

Line A bus arrives at the bus stop = every 25 minutes

Line B bus arrives at the bus stop = every 15 minutes

We need to find the number of minutes that both will be at the bus stop again.

For this we will find the L.C.M. of 25 and 15.

Since L.C.M. of 25 and 15 = 75

So, Both will be stop at the bus stop again after 75 minutes.
