Question

what is the angle traced by hour hand in 15 minutes​

Answer 1

Step-by-step explanation:

Here the time is 9:15 which is (9 +15/60) = 37/4 hours. Since eachhour corresponds to 30 degrees, we multiply 30 to get (37/4)(30) = 277.5 degrees. Since the hour handis at 277.5 degrees and the minute hand is at 90 degrees, we can subtract to get the angle of separation.

Answer 2

Answer:

The angle traced by an hour hand in 15 minutes is 7.5°

Step-by-step explanation:

The angle traced by hour hand incomplete round =360°

The angle traced in one hour=360/12=30°

So, the angle traced in 15 minutes=30°/4=7.5°(Since,15 minutes are one/fourth of an hour)
