Henry wanted to know how fast his pet tortoise could walk.

First, he placed a nice leaf of lettuce at one end of his patio. Then, he placed his tortoise 5 meters away from the lettuce and recorded its position and time as it moved toward the lettuce.

The chart below shows Henry's observations.

After 24 seconds, how far away from the starting point was the tortoise?
A. 4 meters
B. 0 meters
C. 2 meters
D. 1 meter
