Question

Tell me the answer plz ......... Bus A and Bus B leave the bus depot at 5 pm. Bus A takes 30 minutes to do its route and bus B takes 35 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.

Answer 1

Answer:

08:30pm

Step-by-step explanation:

Bus A takes 30minutes

Bus B takes 35 minutes

Both of them leave at 5 pm

The time they come together is the LCM of 30 and 35

30 = 2 x 3 x 5

35 = 5 x 7

LCM = 2 x 3 x 5 x 7 = 210

They will come together after 210minutes = 3 hours 30 minutes

They will come together at 8:30pm

I hope it helps
