Answer

(i) As,

1 minute = 60 seconds

then,

3 minute 15 second = 3 minutes + 15 seconds = 3 x 60 seconds + 15 seconds = (180 + 15) seconds = 195 seconds

(ii) As,

1 hour = 3600 seconds

and

1 minute = 60 seconds

then,

5 hour 2 minute 5 second = 5 x 3600 seconds + 2 x 60 seconds + 5 seconds = (18000 + 120 + 5) seconds = 18125 seconds
