If a stone is thrown and travels at a steady speed and covers x metres in 0.2
seconds, what is its speed in metres per seconds and kilometres per hour?

speed in meters per seconds = 5x

speed in kilometers per hour = 18

Step-by-step explanation:

The speed is the distance over the time

Given the speed of the stone x meters in 0.2 seconds

So, speed = = = 5x meters per seconds

To convert from meters per seconds to kilometers per hour :

1 kilometer = 1000 meters ⇒ 1 meters = 0.001 kilometer

1 hour = 3600 seconds ⇒ 1 second = 1/3600 hour

So, 5x meters per seconds = 5x * 3.6 = 18 kilometers per hour

there would only be 50 odd numbers between 1 and 100 so therefor there would be 50 even so that would only be 50 odd numbers.
