Find the difference between 16 and 10. Add the difference to 7.5.

Answer 1

Option B.

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 =
`(10)/(2.5)=4:1`

Now this ratio will be similar to the ratio =
`(x)/(7.5)=x:7.5`

Now
`(4)/(1)=(x)/(7.5)`

x = 7.5×4 = 30 minutes

Therefore, Option B will be the answer.
