Question

a wall clock gets exta 10 second in every 2 minutes if clock is set at 10 am what time it will show at 10 pm​

Answer 1

Answer:

Step-by-step explanation:

if 2 mins = 10 seconds extra

then 1 min = 5 secs extra

then 1 hour = 60 x 5 = 300 secs xtra = 5 mins extra

10 am to 10 pm = 12 hours

1 hour = 5 mins xtra

then 12 hours = 12 x 5 = 60 mins extra = 1 hour extra

so the clock will show at when it is 11 pm in other clocks  it will show in that clock 10 pm
