Express in second 1. 3 minute 15 second and 2. 5 hour 2 minute 5 second.

Answer»

1. 3 minute = 15 second

1 minute = 60 second

3 minutes 15 second = 60 × 3 + 15

= 180 + 15

= 195 seconds

2. 1 minute =60 second

2 minutes =2 × 600 = 120 second …...........(1)

1 hour 3600 second

5 hour 3600 × 5 = 18000 second ….............(2)

5 hour 2 minutes and 5 second

= 18000 + 120 + 5 = 18125 seconds
