Question

Where will the hand of a clock stop if it starts at 4 and make half of a revolution clockwise?

Answer 1

The clock half revolution will complete in 10:00

Answer 2

Given,

Hand of the clock starts at 4

To find,

The position of the hand of the clock after half of a revolution clockwise.

Solution,

We can simply solve this mathematical problem by using the following mathematical process.

Now,

In a clock, 1 complete revolution means 12 hours

So,

½ revolution = 12 × ½ = 6 hours

Now,

The hand is spinning in clockwise direction so we need to add the time span of ½ revolution with the starting time, in order to get the time at which of the hand of the clock, stops.

Thus,

The current position of the hand of the clock :

At = 4 + 6 = 10

(This will be considered as the final result.)

Hence, the hand of the clock will stop at 10
