Question

A car moves at 45 miles per hour. The time and the distance it travels are recorded.What is the dependent variable?A.the carB.the timeC.the distanceD.45

Answer 1

So,

We know that the car moves at 45 miles / hour.

The distance can be described as:

`d=st`

Where s is the speed of our car and t is the time. If we replace:

`d=45t`

As you can see, the dependent variable of this equation is the distance, and it depends of the time travelled.
