Question

A wacth gains 42 seconds in 3 days and 8 hours. How long would it take to gain 2 minutes 6 seconds

Answer 1

Answer:

It would take 20 days, 17 hours, and 36 minutes to gain 2 minutes, 6 seconds.

Answer 2

It will take 10 days.

• Given data :

The wacth gains 42 seconds in 3 days and 8 hours or in 80 hours. ( Term of unit conversion = 24 hours = 1 day).

• Now,the necessary time to gain by the watch is 2 minutes 6 seconds or 126 seconds. ( Term of unit conversion = 60 seconds = 1 minute)

• So,

The watch gains 42 seconds in = 80 hours

The watch gains 1 second in = 80/42 hours

The watch gains 126 seconds in = 80×126/42 = 240 hours.

So,the watch will gain necessary time in 240 hours or in 10 days. (Term of unit conversion = 24 hours = 1 day). (Answer)
