Algebra Difficulty 1.1 Junior Find the answer Canada

If 7:30 a.m. was 16 minutes ago, in how many minutes will it be 8:00 a.m.?

Pick one

Solution

If 7:30 a.m. was 16 minutes ago, then it is currently 30+16=4630+16=46 minutes after 7:00 a.m., or 7:46 a.m.

Since 8:00 a.m. is 60 minutes after 7:00 a.m., then it will be 8:00 a.m. in 6046=1460-46=14 minutes.
