Question

the graph shows the relationship between the number of minutes maria spent jogging on a treadmill and the distance she jogged.
miles on the treadmill
what was her speed?
0.1 mile per minute
0.5 mile per minute
5 miles per minute
10 miles per minute

Explanation:

Step1: Recall speed formula

Speed is calculated as \( \text{speed} = \frac{\text{distance}}{\text{time}} \).

Step2: Identify a point on the graph

From the graph, when time \( x = 30 \) minutes, distance \( y = 3 \) miles (by looking at the grid where the line passes through \( (30, 3) \)).

Step3: Calculate speed

Using the formula, \( \text{speed} = \frac{3}{30} = 0.1 \) mile per minute.

Answer:

0.1 mile per minute
