What is the elapsed time between the 0-m mark and the 40-m mark

a) 4.0 s

b) 16 m/s

c) The distance covered between 4 - 5 s is four times the distance covered between 4 - 5 s

d) Equal distance are covered between 0 - 4 s and 4 -5 s

Note: The question is incomplete. The complete question is as follows;

Refer to the chart below that has data about a moving object to answer the following questions.

Time Elapsed         0.0s   1.0s    2.0s    3.0s    4.0s    5.0 s

Distance Traveled 0.0m 10.0m 20.0m 30.0m 40.0m 80.0 m

a. What is the elapsed time between the 0-m mark and the 40-m mark?  

b. How large is the average velocity of the object for the interval from 0-5 s ?  

c. How does the interval of 3-4 s compare with the interval from 4-5 s in terms of distance?    

d. How does the interval of 0-4 s compare with the interval from 4-5 s in terms of distance?    

Explanation:

a. From the data provide, time elapsed between the 0 m - 40 m mark is 4.0 s

b. Average velocity = total distance/ total time

average velocity = 80 m/ 5.0 s = 16.0 m/s

c. Distance covered between 3 - 4 s = 40 m - 30 m = 10 m

Distance covered between 4 - 5 s = 80 m - 40 m = 40 m

The distance covered between 4 - 5 s is four times the distance covered between 4 - 5 s

d. Distance covered between 0 - 4 s = 40 m - 0 m = 40 m

Distance covered between 4 - 5 s = 80 m - 40 m = 40 m

Equal distance are covered between 0 - 4 s and 4 -5 s

i don't know that i agree with that but what's the question ?
