Question

Find the unit rate if Mrs. Arnold drove 270 miles in 6 hours? Include details.

Answer 1

Unit rate is the amount of the one thing in 1 of the other things.
An example (not this problem):
180 miles in 3 hours is 60 miles per hour

Answer 2

so 270 divided by 6?

Answer 3

270/6 = x/1 (270 miles in 6 hours = x miles in 1 hour)
cross multiply
270x = 6
x = 270/6
x = 45
Mrs. Arnold drove 45 miles in 1 hour (so unit rate is 45 mph )
