Question

An object moves 18m in the first 3second 22m in the next 3second and 14m in the last 3second what the average speed

Answer 1

Answer: 6 m/s

Given: Distance travelled by the object = 18 m, 22 m and 14 m

           Time taken by the object = 3 s, 3 s, 3 s

To find: Average speed of the object.

Explanation:

Average speed is the ratio of the "total distance travelled by an object", to the "total time taken by the object" to cover the distance.

$\text{Average speed}=\frac{\text{Total distance taken}}{\text{Total time taken}}$

Total distance taken by the object = 18 m+22 m+14 m

                                                          = 54 m

Total time taken by the object = 3 s + 3 s + 3 s

                                                  = 9 s

Therefore,

$\text{Average speed}=\frac{\text{54 m}}{\text{9 s}}=6m/s$

Hence, the average speed of the given object is 6 m/s.
