Final answer:
Coach Matta is faster than Mrs. Rush by 10 yards per second, as he can run 30 yards per second, compared to her 20 yards per second.
Step-by-step explanation:
To determine who is faster between Mrs. Rush and Coach Matta, we need to compare their speeds. Speed is calculated as the distance traveled divided by the time it takes to travel that distance. For Mrs. Rush, her speed is 100 yards in 5 seconds, which is 20 yards per second. For Coach Matta, the speed is 180 yards in 6 seconds, which is 30 yards per second.
Therefore, Coach Matta is faster than Mrs. Rush.
To find out by how much Coach Matta is faster, we compare their speeds directly: Coach Matta's speed is 30 yards per second while Mrs. Rush's speed is 20 yards per second.
The difference in speed is 30 - 20 = 10 yards per second. So, Coach Matta is 10 yards per second faster than Mrs. Rush.
