Superman the Escape in CAlifornia is the fastest roller coaster in the world. Riders fall 415 feet in 7 seconds. Speeds reach a maximum of 100 miles per hour.
If x represents the average rate of fall of the roller coaster, write an expression to represent the situation. (Hint: Use the distance formula d=rt.)
What is the average rate that riders fall in feet per second?
