It's 3.15 pm and Adam needs to post the parcel. The journey to the post office takes 36 minutes. Adam queues in the post office for 13 minutes. Give your answer in 24-hour clock format. What time does Adam get back home? :

16:40

Step-by-step explanation:

To convert 3:15 PM to 24-hour time, we remember that PM is after noon. This means we add 12 to 3 for the hour; this gives us 15:15.

Add 36 minutes to this; we get 15:51.

Add 13 minutes to this; it takes 9 minutes to get to 16:00, which leaves 4 minutes; this gives us 16:04.

Adding 36 minutes to this, we have 16:40.

3:15 + 36 minutes = 3:51

3:51 + 13 minutes = 4:04

4:04+36 minutes = 4:40

answer is

4: 40 pm
