Phillip watched a beach vollyball game from 1 p. M. To 1:15 p. M How many degrees did the minute hand turn?

90°

Step-by-step explanation:

A full rotation on a clock would be 360° like a normal circle and this would represent a full hour.

When it comes to 15 minutes therefore, to find the number of degrees the time would turn, find out the proportion of an hour that 15 minutes is then relate it to 360°.

= 15 mins / 60 mins

= 1/4 hours

If an hour is 360°, 1/4 hours must be:

= 1/4 * 360

= 90°

a = 11 : 4

b = 38

c = 1 for every 6
