Enter the missing numbers in the boxes to complete the table of equivalent

A = 2 , B = 10  and  C = 18

Step-by-step explanation:

Let the the missing numbers in the boxes are: A , B  and C.

Given:

Time  :   Distance

 A      :       3

 6      :       9

 B      :       15

12      :       C

From the second raw, we can deduce that:

When the time = 6, the distance = 9

We will use the ratio and proportional to find A , B and C

So,

A/6 = 3/9  ⇒ A = 6 * 3/9 = 2

6/B = 9/15 ⇒ B = 6*15/9 = 10

6/12 = 9/C ⇒ C = 9*12/6 = 18

So, A = 2 , B = 10  and  C = 18

its c or d   take a lucky guess my dude
