Answer:
Explanation:
Alright, lets gets started.
We have given the distance as 100 meters.
The time for completing this distance is 20 seconds.
The formula for calculating speed is :
![speed=(distance)/(time)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/7gzx4iml15gaaazw2kr88crmygjkulbo0g.png)
Hence plugging the values of distance and time in formula,
meters per second
We could further simplify this speed to 5 meters per second, but as the expression is asked in question, we will given answer
meters per second.
Hope it will help :)
