Question

How do you convert hours, minutes and seconds to seconds?

Answer 1

Explanation:

1 Hour=60 minutes

1 minute = 60 seconds

So for example,

15 hours= 15x60 minutes =900 minutes

15 hours = 15x60x60 seconds = 54,000 seconds

Answer 2

Multiply the hours by 60 to convert it to minutes, i.e., 1 hr × 60 = 60 minutes .
Multiply the minutes by 60 to obtain the number of seconds, i.e., 60 minutes × 60 = 3600 seconds .
