Question

if a watch is losing 1.5 minutes for every 12 hours that go by, how many minutes will it lose in one week?​

Answer 1

21 minutes

Explanation:

There are 24 hours in one day, and 7 days per week. Thus there are

(24)(7), or 168, hours in one week, or 14 - 12-hour periods.

Thus, we multiply 14 - 12-hr periods to answer this question:

1.5 minutes / 14 - 12-hour periods)= 21 minutes will be lost in one week.

Answer 2

Hey there! :)

Answer:

21 minutes.

Explanation:

Begin by calculating the number of 12 hour periods in a week.

Each day contains two 12 hour periods. (24 hours/12 = 2)

There are 7 days in a week, therefore:

2 × 7 = 14 times the watch will lose minutes.

Multiply to find the total number of minutes lost:

14 × 1.5 = 21 minutes.
