Question

A clock gains five minutes every hour. what will be the angle traversed by the second hand in one minute

Answer 1

Assume the clock is a circle. Also, assume that the second hand’s continuous motion is the cause of the problem, and not the tick of the minute hand.

The second hand normally traverses 360 degrees in one minute. We would expect, then, for the second hand to travel 21,600 degrees in one hour.

If the clock gains five minutes every hour, the second hand is rotating for an additional five minutes that have not occurred. This means it has rotated 360 degrees five extra times.

21,600∘+(5)(360∘)=23,400∘21,600∘+(5)(360∘)=23,400∘

Divide this by 60 seconds per minute to yield:

390∘

Answer 2

its 390° i think its help u
