A program lasted for 1 hour and 30 minutes. How long is the program in seconds?

Sagot :

1 hour 30 minutes=1.5 hour

Conversion:
1 hour=3,600 seconds

Convert:
[tex]1.5 hours(\frac{3,600 seconds}{1 hour})=5,400 seconds[/tex]

Hope this helps =)

We have the conversions:
1 hour = 60 minutes
1 minute = 60 seconds 

So:
[tex](1hr* \frac{60mins}{1hr} * \frac{60secs}{1min} )+(30mins* \frac{60secs}{1min} ) \\ =3600secs+1800secs=5400seconds[/tex]
