Answer:
Both buses will be at the bus stop at 11am, as said in the question
Then next at 12:10am
Explanation:
Work out the times for bus B until you find one ending in a 0, that's the time they both stop (bus A is every 10 minutes and will always end with a 0)
So bus B:
11.14, 11.28, 11.42, 11.56, 12.10
