Find the unit rate 75 miles miles in 1 1/2

Question

What is the unit rate?

 

Answer 1

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

Answer 2

Mickey.

            I am working on the premise that we are speaking about 1 1/2 hours.

 

You can solve a  question dealing with distance ,time and speed by using the formula

 

D=RT where D = distance R = rate ( speed ) T = time

 

You can solve for any variable if you have the other two

 

D=RT if you are looking for the distance

 

R=D/T if you are looking for the rate or speed

 

T=D/R if you are looking for the time.

 

So plug in the two figures you have and solve for the variable that you are searching for.

 

I hope this helps.
