Question

You clean a community park for 6.5 hours. You earn $42.25. How much do you earn per hour?

Answer 1

6.5 hours is equal to:

60 mins x 6 + 30 mins = 390 mins

------------

42.25 / 390 = 13/120

------------

Now there are 60 minutes in an hour, so what we do is multiply 13/120 by 60 to find out how much you earn per hour...

13/120 x 60 = 6.5

--------------

You earn $6.50 per hour.
