Answer:
B. Find the ratio of minutes to miles, 4:1. Multiply 7.5 by 4.
Explanation:
Look for a pattern within the table.
10 : 2.5
16 : 4
? : 7.5
48 : 12
10/2.5 = 4
16/4 = 4
14/12 = 4
this means that if we multiply 7.5 by 4 we will be able to find the missing number!
Therefore, the answer is B.
Hope this helps! :)
