Question

A clock is set at 8 am. It loses 10 minutes every 24 hours. What will be the true time when the clock shows 11 am?

• A. 10:50 am
• B. 11:10 am
• C. 11:12 am
• D. 11:15 am

Hint:

When a clock loses time, calculate the total loss based on the number of hours passed, then subtract that from the indicated time to get the true time.

Answer 1

The Correct Option is A

The clock loses 10 minutes every 24 hours. Therefore, in 3 hours, the clock will lose: \[ \frac{10 \text{ minutes}}{24 \text{ hours}} \times 3 \text{ hours} = 1.25 \text{ minutes}. \] So, when the clock shows 11 am, the true time will be: \[ 11:00 - 1.25 \text{ minutes} = 10:50 \text{ am}. \] Thus, the correct answer is option A.
