Question

Two buses use the stop at Meadowland Road and Mockingbird Lane. Bus 143 stops every 30 minutes on its express route to downtown. Bus 62 stops there every 8 minutes on its west side route. If they were both at the stop at 6:30 AM, when will they arrive together again?

Answer 1

8:30 AM

Explanation:

Given:

Bus 143 stops every 30 minutes on its express route to downtown

and Bus 62 stops there every 8 minutes on its west side route

both meet at the bus stop at 6.30 AM

to find when they would meet the second time we need to find LCM( 30,8)

= 120

Hence the two buses would meet after 120 minutes that is 2 hours.

Hence they would be meet at 6.30+2= 8.30 AM
