Question

A watch loses 2 hr. 13 min a week. The time it loses in 36 hours is ?

Answer 1

Answer:

28.5 minutes.

Step-by-step explanation:

Time lost by a watch in a week=2hr 13mins=(60+60)+13= 120+13= 133 mins.

The amount of time watch loses in 36 hours=?

find the amount of time watch loses in a day.

a week=7 days÷133 m= 19 minutes a day.

36 hours= a day 24 hours half of a day 12 hours=36 hours.

19+ (19÷2) why did we divide it by 2?

we divided it by two because we need to find the value of time lost in 12 hours too to find the time lost in 36 hours.

19+(19÷2=9.5)

19+9.5= 28.5

therfore time lost in 36 hours is 28.5 minutes.
