The problem asks us to find the velocity of a cheetah between 5 and 15 seconds, given a distance-time graph. We need to express the answer to 1 decimal place.

1. Problem Description

The problem asks us to find the velocity of a cheetah between 5 and 15 seconds, given a distance-time graph. We need to express the answer to 1 decimal place.

2. Solution Steps

First, we need to find the distance travelled at 5 seconds and 15 seconds.

From the graph:

Distance at 5 seconds is approximately 160 meters.

Distance at 15 seconds is approximately 200 meters.

The change in distance, $\Delta d$, is:

$\Delta d = 200 - 160 = 40$ meters

The change in time, $\Delta t$, is:

$\Delta t = 15 - 5 = 10$ seconds

The velocity $v$ is given by:

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

$v = \frac{40}{10} = 4$ m/s

3. Final Answer

4.0 m/s
