One bus leaves a stop every 9 minutes.a second bus leaves the stop every 15 minutes.if they both leave at 1:25 p.m,at what time will they next leave together?
To find the answer, you want to find a common multiple. If you keep multiplying you will eventually find that 45 is the first multiple that both numbers share. The time would be 45 minutes after 1:25
The answer is 2:10 p.m.
