Bus A and Bus B leave the bus depot at 7 am. Bus A takes 30 minutes to do its route and bus B takes 50 minutes to complete its route. At what time are they both back at the bus depot together? Give your answer as a 12-hour clock time.

9:30 am

Step-by-step explanation:

The LCM of 30 min and 50 mins will be given as

30=2*3*5

50=2*5*5

Therefore, the LCM will be 2*3*5*2*5*5=150 mins

Therefore, adding 150 minutes to the starting time

First, converting 150 minutes to hours will need dividing 150 by 60

Therefore, time is 2.5 hours which is 2 hours 30 minutes

Time will be 7.00+2.30=9.30am
