Question

Convert 4 hours 45 minutes to seconds.

• A. 17000 seconds
• B. 17100 seconds
• C. 17200 seconds
• D. 17101 seconds

Answer 1

The correct option is B

17100 seconds

We know that, 1 hour = 60 min
$\therefore$ 4 hours = 4 x 60 = 240 min
4 hours 45 minutes = 240 + 45 = 285 minutes
Also, 1 minute = 60 seconds
$\therefore$ 285 minutes = 285 x 60 = 17100 seconds
