On a standard 12-hour clock, through how many positive degrees does the hour hand move from 9:15 a.m. to 12 noon of the same day?
Express your answer as a decimal to the nearest tenth.
:
Hour hand degrees per hour: 360/12 = 30 degrees/hr
:
15 min = 1%2F4 hr
:
At 9:15 hour hand position: 270 deg + 1%2F4(30) = 277.5 degrees
360 - 277.5 = 82.5 degrees hr hand travels from 9:15 to 12:00
