Question

The graph shows the distances traveled by two hikers over several hours.

Which hiker is moving at a faster rate?

Hiker A

Hiker B

Answer 1

Hiker A is moving faster because in less hours (time) he does more miles (distance).
The slope for Hiker A is greater than B

Answer 2

Hiker A is moving at a faster rate.

Step-by-step explanation:

The rate of change of a line is its slope. Here, the rate represents the division of distance by time, so it represents the speed of each hiker.

From the picture, we can see that the rate of hiker A is greater, that is, hiker A travels a greater distance than hiker B in the same amount of time.
