The speed of a body gives us an idea of how slow or fast that a body is moving. Speed of a body is the distance travelled by it per unit time. The SI unit of speed is metre per second. It is a scalar quantity. The speed of a running car at any instant of time is shown by an instrument called 'speedometer' and the distance travelled by a car is measured by another instrument called 'odometer'.
If an object is moving with speed (S) in time (t), then, the distance (d) will be

A d = S × t
D None of these.

Ans 1:

Class : >Class 6
DISTANCE = TIME × SPEED||| TIME = DISTANCE/SPEED||||| SPEED = DISTANCE/TIME... Use this formula.... So answer is Option (a). I hope this is clear
