Question

A clock runs fast by 5 min per hour. if the clock was set right at 12 noon and the clock shows 6.30 pm now. what is the right time ​

Answer 1

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.
