which statement explains how to find the number of minutes it takes to bike 7.5 miles?
find the ratio of minutes to miles, 4: 1. divide 7.5 by 4.
find the ratio of minutes to miles, 4: 1. multiply 7.5 by 4.
find the difference between 16 and 10. add the difference to 16.
find the difference between 16 and 10. add the difference to 7.5.

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

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 =

Now this ratio will be similar to the ratio =

Now

x = 7.5×4 = 30 minutes

Therefore, Option B will be the answer.

=====================================

explanation

the graph has a slope of 1/3 because each time you move up 1, you go to the right 3. so, slope = rise/run = 1/3. we can cross choice a off the list since we want a slope of 3, rather than 1/3.

the first table shown has a slope of -3. this is because the rise is -6 and the run is 2, so slope = rise/run = -6/2 = -3. note how x increases by 2 each time (run) and y drops by 6 each time (rise). choice b can be eliminated.

the second table has a slope of 3. each time x goes up by 1, the y values increase by 3. slope = rise/run = 3/1 = 3. alternatively you can use the slope formula to prove that the slope is 3 here. use any two rows of values to generate the two points. choice c is one of the answers

the third table also has a slope of 3. let's use the slope formula to prove as such. i'm going to use the first two rows of the table. so i'll use the two points (2,1) and (5,10)

m = slope

m = (y2-y1)/(x2-x1)

m = (10-1)/(5-2)

m = 9/3

m = 3 so we get a slope of 3

choice d is the other answer
