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
Number of Minutes Number of Miles
10 2.5
16 4
? 7.5
48 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.
