The problem asks for the velocity of a cheetah between 5 seconds and 15 seconds, given a distance-time graph. The answer should be given to 1 decimal place.

1. Problem Description

The problem asks for the velocity of a cheetah between 5 seconds and 15 seconds, given a distance-time graph. The answer should be given to 1 decimal place.

2. Solution Steps

First, we need to find the distance traveled at 5 seconds and 15 seconds from the graph.

At 5 seconds, the distance traveled is approximately 175 m.

At 15 seconds, the distance traveled is approximately 200 m.

The change in distance, $\Delta d$, is $200 - 175 = 25$ m.

The change in time, $\Delta t$, is $15 - 5 = 10$ s.

The formula for velocity is:

$v = \frac{\Delta d}{\Delta t}$

Substituting the values:

$v = \frac{25}{10} = 2.5$ m/s.

3. Final Answer

The velocity of the cheetah between 5 and 15 seconds is 2.5 m/s.
