Question

A watch lost 1 minute and 12 seconds in 36 days. how many seconds did it lose per day?

Answer 1

2 sec per day

Explanation:

• To find out how many seconds the watch lost per day, we need to calculate the total number of seconds lost and divide it by the number of days.

First, let's convert 1 minute and 12 seconds to seconds.

I min = 60 sec

• so 1 minute and 12 seconds can be expressed as:

1 minute + 12 seconds

1 × 60 seconds + 12 seconds

72 seconds

• In 36 days, the watch lost a total of 72 seconds.

• To find the number of seconds lost per day, we divide the total seconds lost (72 seconds) by the number of days (36)

72 seconds / 36 days = 2 seconds per day

Therefore, the watch lost 2 seconds per day.

Answer 2

2 seconds per day

Explanation:

First change the minutes to seconds.

1 minute = 60 seconds so

1 minute 12 seconds = 72 seconds

Now divide by the days:

72 seconds / 36 days

2 seconds per day
