If someone earns $10 every 15 minutes, how much do they earn in an hour?

40

Step-by-step explanation:

You multiple 15X4=60

And now multiple 10x4=40

40$

Step-by-step explanation:

There are 60 minutes in an hour so if we break it down:

$10 = 15 minutes

$10 = 15 minutes

$10 = 15 minutes

$10 = 15 minutes

Add them together and we get:

$40 = 60 minutes or 1 hour  

Meaning they would make 40$ in 1 hour.
