Question

Aaron is in his math class. His teacher says that class will be dismissed when the minute hand makes a 90° clockwise rotation. What time will it be when the teacher dismisses the class?
4:05
3:35
3:25
3:20
3:55

Answer 1

Answer:

3:20

Step-by-step explanation:

The 360 degrees clockwise rotation of the minute hand corresponds to 60 minutes.

The 90 degrees clockwise rotation is one-fourth of the 360 degrees, and hence will corresponds to 15 minutes.

The time is now 3:05.

After 15 minutes the time will be 3:20

Therefore the teacher dismisses the class at 3:20
