Question

1. Define speed and its unit?

Answer 1

1. Speed is defined as the distance covered by an object in unit time.
2. It tells us how fast or slow an object moves.
3. speed can be calculated by using formula,

$speed\mathit{=}\mathit{}\frac{\mathit{t}\mathit{o}\mathit{t}\mathit{a}\mathit{l}\mathit{}\mathit{d}\mathit{i}\mathit{s}\mathit{t}\mathit{a}\mathit{n}\mathit{c}\mathit{e}\mathit{}\mathit{c}\mathit{o}\mathit{v}\mathit{e}\mathit{r}\mathit{e}\mathit{d}}{\mathit{t}\mathit{o}\mathit{t}\mathit{a}\mathit{l}\mathit{}\mathit{t}\mathit{i}\mathit{m}\mathit{e}\mathit{}\mathit{t}\mathit{a}\mathit{k}\mathit{e}\mathit{n}}$
