Question

An object travels 16 m in 4 s and then another 16 m in 3 s. What is the average speed of the obiect? ​

Answer 1

Answer:

The average speed of the object is 5.33 m/s.

Explanation:

Velocity V = \bold{=\frac{\text {distance}}{t i m e}}=

time

distance

Distance traveled by an object in part 1, D1 = 16 m

Time taken by an object (in part 1), T1 = 4 seconds

Distance traveled by an object in part 2, D2 = 16 m

Time taken by in part 2, T2 = 2 seconds

Average speed of an object =\frac{D 1+D 2}{T 1+T 2}=

T1+T2

D1+D2

= 16 + 16 / 4 + 2 = 5.33 m/s

Answer 2

Answer:

answer is 4.57 m/s

Explanation:

Total distance = 16m + 16m = 32m

total time = 4s + 3s = 7s

average speed = total distance/total time

                          =  32/7

                          =  4.57 m/s
