Okay, let's solve this step-by-step:
* We are given points on a coordinate plane showing Richard's position after 2, 3 and 4 seconds on the zip line:
(2 seconds, 22 meters)
(3 seconds, 33 meters)
(4 seconds, 44 meters)
* From this we can see that in:
2 seconds he traveled 22 meters
3 - 2 = 1 second he traveled 33 - 22 = 11 more meters
4 - 3 = 1 second he traveled 44 - 33 = 11 more meters
* Since he traveled 11 meters in each 1 second interval, we can conclude that he travels 11 meters in 1 second.
So the answer is: Richard travels 11 meters on the zip line in 1 second.
