Question

2 hours 3 minutes = ____ seconds

• A. 7280 seconds
• B. 7380 seconds
• C. 7203 seconds
• D. 7260 seconds

Answer 1

The correct option is B

7380 seconds

1 hour = 60 minutes

1 minute = 60 seconds

$\therefore$ 1 hour = 60 $\times$ 60 = 3600 seconds

2 hours = 3600 $\times$ 2 = 7200 seconds

3 minutes = 3 $\times$ 60 = 180 seconds

$\therefore$ 2 hours 3 minutes is:

$7200seconds\underset{–}{+180seconds}\underset{–}{7380seconds}$
