Question

a car travels a constant speed for 4hours if it covers a distance of 320km.calculate its speed​

Answer 1

Given :

▪ Distance covered by car = 320km

▪ Time interval = 4h

To Find :

▪ Speed of car.

Concept :

☞ Speed is defined as the ratio of distance travelled to the time taken.

☞ It is a scalar quantity.

☞ It has only magnitude.

☞ It can't be negative or zero.

☞ SI unit : m/s

☞ Dimension formula : [L(1)T(-1)]

Calculation :

→ v = d / t

→ v = 320 / 4

→ v = 80kmph

Answer 2
