A watch lost one minute 18 seconds in 39 days.

Question

How many seconds did it lose per day?

Answer 1

To find out how many seconds the watch lost per day, we first need to convert the total loss of time into seconds.

1 minute = 60 seconds, so: 1 minute 18 seconds = 60 seconds + 18 seconds = 78 seconds.

Now, we know the watch lost a total of 78 seconds in 39 days. To find the loss per day, we divide the total loss by the number of days:

\[ \text{Loss per day} = \frac{\text{Total loss in seconds}}{\text{Number of days}} = \frac{78 \text{ seconds}}{39 \text{ days}} = 2 \text{ seconds per day}. \]

Therefore, the watch lost 2 seconds per day.
