Question

There is a circular path around a sports field mitansh takes 15 min to complete one round while poonam takes 20 mins to complete one round suppose they both start at the same point and at the same time 8'o clock in the morning and go in the same direction after how many minutes they meet again at the starting point? how many rotation each has complete?

Answer 1

Answer:

They would meet after 1 hour i.e 60 mins. Mitansh would complete 4 rounds and Poonam would complete 3 rounds.

Step-by-step explanation:

Since they start at same point and at same time and in same direction, we would take LCM of 15 and 20 which is 60. So they would meet after 60 mins i.e 1 hour. Since Mitansh take 15 mins for 1 round, no.of rounds for him = 60/15=4 and Poonam take 20 mins for 1 round, no.of rounds for her =60/20=3 rounds
