Answer:
B) Find the ratio of minutes to miles, 4:1. Multiply 7.5 by 4
Step-by-step explanation:
A bicyclist rides the same number of miles every minute. The ratio table below shows the number of miles she rides during certain amounts of time.
Biking Times and Distances    Â
Number of Minutes     Number of Miles
10 Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â 2.5
16 Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â 4
? Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â 7.5
48 Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â 12
Which statement explains how to find the number of minutes it takes to bike 7.5 miles?
B) Find the ratio of minutes to miles, 4:1. Multiply 7.5 by 4....
Answer:
Option B.
Step-by-step explanation:
A bicyclist rides the same number of miles in one minute.
Ratio table is given as
Number of minutes   Distances (miles)
    10                  2.5
    16                  4
    x                   7.5
    48                  12
We have to find the number of minutes taken by a biker to bike 7.5 miles
So the ratio between minutes to the distance biked will be = [tex]\frac{10}{2.5}=4:1[/tex]
Now this ratio will be similar to the ratio = [tex]\frac{x}{7.5}=x:7.5[/tex]
Now [tex]\frac{4}{1}=\frac{x}{7.5}[/tex]
x = 7.5×4 = 30 minutes
Therefore, Option B will be the answer.
