Jessica 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. Based on her result, is the relationship between m, the speed of the car in miles per hour, and
k, the speed of the car kilometers per hour proportional?
