Answer 2

Answer:

It will take 12 seconds to strike 8 times at 9 O'clock.

Explanation:

It is given that;

A clock takes 3 seconds to strike 3 O'clock.

So,

To strike at 3 O'clock, the first strike will be at time = 0;

and the other strike will be done in 3 seconds.

That means,

For every time, the first strike will be at time = 0;

So,

At  9 O'clock, first, it will strike at time = 0;

and there will be 8 strikes, which is one less than the time.

So,

Time taken to strike 8 times at  9 O'clock  = (8×3) ÷ 2

Time taken to strike 8 times at  9 O'clock = (24) ÷ 2

Time taken to strike 8 times at  9 O'clock = 12 seconds.

Therefore,

It will take 12 seconds to strike 8 times at 9 O'clock.
