Answer: 3:08
Explanation:
They started riding at 2:47 and reached the soccer field 21 minutes later.
The time they go to the field is therefore:
= 2:47 + 21 minutes
= 3:08
Adding time:
First find out the number of minutes needed to take 2:47 to 3:00:
= 60 minutes in an hour - 47
= 13 minutes
Then remove the 13 minutes from the 21 minutes of riding:
= 21 - 13
= 8 minutes
Add this 8 to 3:00:
= 3 + 8
= 3:08
