Question 2

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.
Based on her results, which statement describes the relationship between $m$, the speed of the car in miles per hour, and $k$, the speed of the car in kilometers per hour?

Accepted Answer

The relationship is proportional because the ratio of $m$ to $k$ is constant.

Answer

The relationship is proportional because the difference between $m$ and $k$ is constant.

Answer

The relationship is not proportional because the ratio of $m$ to $k$ is constant.

Answer

The relationship is not proportional because the difference between $m$ and $k$ is constant.
