Question

2.

Archbridge Bus Company have a very small road on the exit of their bus garage. This means they need to be
aware of when this road will be used by multiple buses.
The 157 bus leaves every 55 minutes.
The 183 bus leaves every 77 minutes.
All buses start service at 9:00.
Apart from when the buses leave at 9:00, at what time will both be leaving the garage at the same time?​

Answer 1

3:25

Explanation:

55=11*5

77=11*7

LCM = 11*7*5

=385 min

therefore

9:00+6:25 = 15:25 i.e 3:25 in time
