45 minutes in ¾ hour

Answer

1 minute = 60 seconds.

½ minute = 30 seconds.

¼ minute = 15 seconds.

5¼ minutes = 5 × 60 + 15 = 300 + 15 = 315 seconds.

 

Example 2

Ahmed starts work at 9 a.m. and finishes at 4:30 p.m.

For how many minutes is he at work?

 

Answer

From 9 a.m. to 4 p.m. is 7 hours so Ahmed is at work for 7½ hours.

1 hour = 60 minutes.

½ hour = 30 minutes.

 

7½ hours = 7 × 60 + 30 = 420 + 30 = 450 minutes.
