Answer:
space = 66.24 [m]
Step-by-step explanation:
To solve this problem we must remember that the average speed is defined as the relationship between a space traveled over a certain time.

where:
space [m]
Av = average velocity = 3.6 [m/s]
time = 18.4 [s]
![space = 3.6*18.4\\space = 66.24 [m]](https://img.qammunity.org/2021/formulas/physics/college/vqn7zispmyekwofx5pvu220885id0yms0e.png)
