Verda used a sensor to measure the speed of a moving car at different times. At each time, the sensor measured the speed of the car in both miles per hour and kilometers per hour. The table below shows her results

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.

4/6 = 2/3

so it should take 3/3 hours per man. so 9 hours is the answer 3*3 =9
