Question:- Alana biked 12 miles in 48 minutes. What is Alana's speed in miles per minute?

Answer:-

Set up a proportion.

12/48 = 1/x

Cross multiply.

12*x = 12x
48*1 = 48

12x = 48

12x/12 = 48/12 

x= 48/12
x= 4

Now, we have our final answer. x = 4

Final answer:- Alana bikes 4 miles per minute.
