Bus a and bus b leave the bus depot at 4pm. Bus a takes 15 minutes to do its route and bus b takes 35 minutes to complete its route. at what time did they both get back to the bus depot together. give your answer as a 12-hour clock time

4.35pm is the later time, both buses were together back at the depot.

Reasons;

As bus b did not return his return route until 35 minute after departure.

We can say this was a return route taking 35 minute as the question does not point out length of time getting back. We therefore state it is a return route in the workings to explain how we found the answer.

Step-by-step explanation:

4.00 + 0.35 = 4.35 = b

4.00 + 0.15  = 4.15 = a

4.35 is the later time.

what is the original number? you forgot to add it.
