Question

An object moves 80m in the first 3 second, 22m
next 3 sec, 14 m in last 3 sec. What is the average
​

Answer 1

Explanation:

average speed = total distance/ total time taken

avg s = 80 + 22 + 14/ 3+3+3

avg s = 116/9

avg s = 12.86 m/s

Answer 2

answer: 12.88888..m/s

Explanation:

80m + 22m + 14m= 116m ( total distance taken)

3s+3s+3s= 9s( total Time taken)

average speed= total distance taken / total Time taken

116/9

= 12.88888..m/s
