Question

The 89 bus comes every 8 minutes. The 368 bus comes every 12 minutes. Both buses are at the same stop at 9 am. At what time will they be at the same stop.

Answer 1

9:24 am

Explanation:

89 bus = 8 minutes

368 bus = 12 minutes

Find the lowest common multiple(L.C.M) of 8 minutes and 12 minutes

8 minutes = 16, 24, 32, 40, 48

12 minutes = 24, 36, 48, 60

The L.C.M of 8 minutes and 12 minutes is 24 minutes

Both buses are at the same stop at 9 am.

The next time both buses will be at the same stand = 9 am + 24 minutes

= 9:24 am
