The problem asks us to find the velocity of a cheetah between 5 and 15 seconds, given a distance-time graph. We need to calculate the velocity in meters per second (m/s) and round the answer to one 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 calculate the velocity in meters per second (m/s) and round the answer to one decimal place.

2. Solution Steps

First, we read the distance traveled at 5 seconds and 15 seconds from the graph.

At 5 seconds, the distance traveled is approximately 170 meters.

At 15 seconds, the distance traveled is approximately 210 meters.

The change in distance is $210 - 170 = 40$ meters.

The change in time is $15 - 5 = 10$ seconds.

The velocity is calculated as the change in distance divided by the change in time.

$Velocity = \frac{Change\ in\ Distance}{Change\ in\ Time}$

$Velocity = \frac{40\ meters}{10\ seconds}$

$Velocity = 4\ m/s$

3. Final Answer

4.0 m/s
