What is the unit rate?

75 miles in 1 1/2 hours

find the unit rate

75/(1 1/2)=75/(3/2)=(75)(2/3)/(3/2)(2/3)

=(75)(2/3)/1

=(75)(2/3)

(75)(2/3)=(75*2)/3

=150/3

=50 miles/hour

you can also simplify:(75/3)*2=25*2=50

you can also change 1 1/2 to 1.5 which gives 75 miles/1.5 hours

75 miles/1.5 hours=750 miles/15 hours=50 miles/hour
