Question 8
Which of the following relations is correct?

1. Speed = $Distance\ast Time$
2. Speed= $\frac{Distance}{Time}$
3. Speed= $\frac{Time}{Distance}$
4. Speed = $\frac{1}{Speed\ast Time}$

Answer 1

Speed is defined as the distance covered in unit time. So it can be expressed as $Speed=\frac{Distance}{Time}.$ The basic unit of speed is $\frac{m}{s}.$
