Question 1143387: SAMMY has a faulty clock. Every 15 degrees that one of the hands moved, 5 minutes passes. If a hand is initially 5:35pm, in how long will the hand be at the same position?
A)65 min
B)2 hour
C)1hour
D)45 min Found 2 solutions by josmiceli, greenestamps:Answer by josmiceli(19441) (Show Source):
The minute hand should move 360 degrees in 60 minutes, a rate of 6 degrees per minute.
Sammy's faulty clock has a minute hand that moves 15 degrees in 5 minutes, a rate of 3 degrees per minute.
The minute hand on his clock moves half as fast as it should; since it is normally 1 hour between times when the minute hand is in the same position, it will be 2 hours on Sammy's clock.
