Question

The graph shows the total distance A tour group travels as a function of time, measured in days.

What is the rate of change of this function?

Answer 1

35 miles per day

Answer 2

35 miles per day

Explanation:

The rate of change of distance is given by the following expression:

`rate = (change in quantity)/(time)`

The change in quantity = change in distance

The time is given in days

Calculating the gradient or change of slope =
`(100-0)/(3)`

= 33.33 miles/day

The value is closer to 35 miles/day
