Sanaa Sheppard · Answer 1

Answer: B) 2.5 m/s

Explanation: Find the average of the time and distance, and see how far they go in only 1 second.

1 + 2 + 3 + 4 + 5 = 15

15 divided by 5 = 3

3 seconds

2 + 5 + 7 + 10 + 12 = 36

36 divided by 5 = 7.2

7.2m per 3 seconds.

7.2 divided by 3 = 2.4

Therefore, the answer is technically 2.4m/s
