Question

an object moves 10m in 4s then truns left and moves 20 m in next 5 s .what is the average speed of the object?​

Answer 1

Answer:

3.33 m/s

Explanation:

An object moves 10 m in 4s then turns left and moves 20m in next 5s

Total distance travelled = 10+20 = 30m

Total time taken= 4+5 = 9 s

Average Speed = 30/9 = 3.33 m/s

Answer 2

Average speed=10m+20m/4s+5s
A=30/9
A=3.33m/s

Answer=3.33m/s
