Question

The clock shows the time ( 9:00 ) that Candace leaves for a bicycle ride. She rides for 1/2 hour.

Through how many degrees does the minute hand turn while Candace is on her ride?

Answer 1

180

Explanation:

because half a circle is 180 degrees and since 1/2 hour means she returns at 9:30 the minute hand would have to move half of a circle around the clock

Answer 2

180°

Explanation:

1/2 hour = 30 minutes

1 hour is 360° degrees.

1/2 hour = 360 ÷ 2 = 180°
