Question

Who discovered speed?

Answer 1

1. Speed can be defined as the distance covered by an object per unit time. Its S.I. unit is $meterpersecond$ ($\mathrm{m}/\mathrm{s}$).
2. Speed can be expressed by the expression, $v=\frac{d}{t}$. Here, $v$ is the speed, $d$ is the distance and $t$ is the time.
3. Galileo Galilei was an Italian scientist from the $16th$ century who is credited for discovering the concept of speed.
