Question

A person travels a distance of 72 m in 4 second calculate average speed

Answer 1

Answer:

Hii There!!!

Given, distance travelled = 72m

Time taken = 4s=)

Since, Speed= distance travelled/time taken

                     =72/4

                     =18m/s

Hope it helps

Answer 2

▶ Solution :

Given :

▪ Distance travelled = 72m

▪ Time taken = 4s

To Find :

▪ Average speed of person

Concept :

✏ Average speed is defined as the ratio of total distance travelled to the total time taken.

✏ Average speed is a scalar quantity.

✏ It has only magnitude.

✏ Distance is called as actual length of path.

Calculation :

$\implies\sf\:v_{av}=\dfrac{total\:distance\:travelled}{total\:time\:taken}\\ \\ \implies\sf\:v_{av}=\dfrac{72}{4}\\ \\ \implies\boxed{\bf{\pink{v_{av}=18\:mps}}}$
