Clock A shows when Sana started a mock test and clock B shows when she finished (same afternoon). Through how many degrees did the hour hand turn during the test?

Question

Accepted Answer

78°. A shows 1:10 and B shows 3:46, so the test took 156 minutes. The hour hand turns 0.5^° per minute: 156×0.5^°=78^°. (936° is how far the minute hand turned.)
