Answer» Answer: I suppose that at 5 am the “crazy” CLOCK is synchronized with a “normal” one. From 5 am to 10 am the time elapsed in the “crazy” clock is 10 am - 5 am = 5 hours Then 5 X (60 + 5) = 300 + 25, which means the “crazy” clock is 25 MINUTES ahead of the “normal” one. Then in the “normal” clock the time elapsed from 5 am to 10 am is (5 x 60) - 25 = 275 minutes, or 275 / 60 = 4,58 hours = 4 hours + 0,58 of an hour 0,58 x 60 = 34,8 minutes Then the time in the “normal” clock is (5 am + 4h34,8min) = 9h34,8min rounded to 9h35min. |
