Question

What was Bear B's average speed in
m/min? No units required for answer.

Answer 1

Given:

Graph of positions of Bear A and Bear B.

To find:

The average speed of Bear B in m/min.

Solution:

From the graph it is clear that initial point of graph of Bear B is (0,100) and the end point is (60,2800).

The average speed of Bear B is

`m=(y_2-y_1)/(x_2-x_1)`

`m=(2800-100)/(60-0)`

`m=(2700)/(60)`

`m=45`

Therefore, the average speed of Bear B is 45 m/min.
