Question

Which expression calculates the speed in meters per second of an object that travels a distance of 100 m every 20 s?

Answer 1

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)`

Hence plugging the values of distance and time in formula,

`speed=(100)/(20)` 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
`(100)/(20)` meters per second.

Hope it will help :)
