Your class started at 12: 12pm and ended at 12: 50pm. what angle did the minute hand of a watch sweep through during the class? a. 228. b. 132. c. 168. d. 153.

recall that a circle has a total of 360°.

now the clock has 60 minutes, how many degrees are there between each minute? well, that'd be 360°/60, which gives us 6° for every passing minute.

the class started at 12:12, went through to 12:50, that's 38 minutes, and since every passing minute is 6°, that'd be 38 * 6.

i did it myself and i got 4.2 (b) hope its right
