Question

A clock takes 7 seconds to ring bell of 7 hours clock. How long will it take for the same clock to ring bell at 10 hours clock?

Answer 1

Answer:

To strike 7 times, the clock goes

bong-bong-bong-bong-bong-bong -bong

Notice that there are only 6 dashes between those 7 bongs. Therefore

there are only 6 time intervals between the 7 bongs.

So we divide 7 seconds by 6 and get each time interval between bongs

1.16 seconds.

To strike 10 times, the clock goes

bong-bong-bong-bong-bong-bong-bong-bong-bong-bong

Notice that there are only 9 dashes between those 10 bongs. Therefore

there are only 9 time intervals between the 10 bongs.

Since each time interval is 1.16 seconds, 9 of those time intervals between

bongs is 9x 1.16 seconds which equals 14.94 seconds.
