Question

.An object travels 20 m in 2 s and then another 16 m in 2 s. What is the average speed of the object? with steps ​

Answer 1

Explanation:

Total distance =20+16 m =36m

Total time =2+2 s= 4s

$average \: speed = \frac{total \: distance}{total \: time} \\ = \frac{36}{4} = 9m \: per \: sec$

Answer 2

Answer:

Given:

Case I :

Distance = 20 m

Time = 2 s

Case II :

Distance = 16 m

Time = 2 s

To find: Average Speed of the object

Solution: Average speed = Total distance / Total time taken

   = 36/4 = 19 m/s
