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

Answer:

Step-by-step 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 :

$speed=\frac{distance}{time}$

Hence plugging the values of distance and time in formula,

$speed=\frac{100}{20}$ 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 $\frac{100}{20}$ meters per second.  

Hope it will help :)
