Question

Solve :- An object move
18 m in first 3s and 22m in next 3s ,while it travel 14m in last 38 calculate average speed.​

Answer 1

Answer:

54/44=27/22m/s

Explanation:

average speed is total distance traveled in total time

so it is 54/44 or 27/22m/s

Answer 2

The average speed of the object will be 6 m/s.

Explanation:

By definition, 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, or,

$\sf {Average Speed } = \frac { \text {Total distance travelled } } { \text { Total time taken}}$

According to the question,

Total distance travelled by an object

= 18m + 22m + 14m = 54m

Total time taken by the object to cover 54m

= 3s + 3s + 3s = 9s

∴ Average Speed $\sf =\frac {(54 m)}{(9 s)}$

= 6 m/s (Ans.)

• Thus, the average speed of the object will be 6 m/s.
