How many MINUTES is 9000 SECONDS

And then how many hours is the answer?

150 MINUTES

because there are 60 seconds in a minute:
9000/60 = 150

To find minutes we divide our seconds by 60 because there are 60 seconds in a minute.

9000/60 = 150 min

Now to convert 150 min to hours we simply divide by 60 again because there are 60 minutes in a hour.

150/60 = 2.5 hrs

Steps:
(9000s/60)m
=150m
(150m/60)h
=2.5h
2.5h or 2h30m

9000 seconds
= 9000/60 minutes
= 150 minutes
= 150/60 hours
= 2 1/2 hours

9000 seconds

1 hr = 60*60 seconds
= 3600 s

9000/3600 hrs
= 2.5 hrs

15 , one five, fifteen minutes.
