Question

A wall clock is placed in a room. It chimes 8 times at 8 o'clock. A person "X" present outside the room listens the 8 beats of chimes in 8 seconds. Assume that each chime of the wall clock takes equal time. To listen 11 chimes at 11 O'clock how much time will be required by person "X".​

Answer 1

Answer:11

Step-by-step explanation:

Answer 2

Given :

A wall clock chimes the number of times at 8 o'clock = 8 times

The number of intervals in 8 beats = 7 intervals

To Find :

Time taken by 11 chimes at 11 o'clock

Solution:

There are 7 intervals = 8 seconds

time of 1 interval = $\frac{8}{7}$ seconds

The number of intervals in 11 chimes = 10 intervals

Time would be required for 10 intervals = $\frac{8}{7}\times 10$

                                                                  = 11.4285 ≈ 11.43 seconds

To listen 11 chimes at 11 o'clock 11.43 seconds will be required by person X.
