Answer:
Option A
Step-by-step explanation:
If the speed of a car in miles per hour (m) is proportional to the speed in kilometers per hour (k),
m ∝ k
m = ck
Here, c = Proportionality constant
Therefore, c = should be constant for each value given in the table.
For m = 11 and k = 17.699,
c =
c = 0.6215
For m = 26 and k = 41.834,
c =
c = 0.6215
For m = 34 and k = 54.706,
c =
c = 0.6215
Therefore, c is constant for each value of m and k.
Option A will be the correct option.
