Question

A boy starts running at 6:00 am and stops at 7:00 am. For how many seconds did he run?

• A. 360 secs
• B. 3000 secs
• C. 600 secs
• D. 3600 secs

Answer 1

The correct option is D 3600 secs

From 6:00 am to 7:00 am, the time elapsed is 1 hour.
$1\text{h}=60\text{mins}1\text{min}=60\text{secs}\therefore 1h=60\times 60\text{secs}=3600\text{secs}$
Thus, the boy ran for 3600 seconds.
