Question

What is the unit rate in dollars per hour if u have 3.5 hours equals $10

Answer 1

3.5 hours equal $10
3.5 hours= 7/2 hours

if 7/2 hours = $10
1 hour =
`(10)/( (7)/(2) ) = 10*(2)/(7) = (20)/(7)` dollars

Unit rate = $(20/7) per hour

Answer 2

Okay. So this is a simple division problem. All you need to do is divide 10 by 3.5. This will figure out how much you spend per single hour. you'll come up with around 2.855. So I'd round down, and say $2.85 per hour.
