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?

  • algebra -

    average rate of fall is average speed.

    average speed= distance fell/time

    Thanks but this doesnt really help me answer my question.

  • algebra -

    goodness. what is distance fell, and the time of fall. That is in the problem.

  • Algebra -

    It is simply:
    1.) 415 = 7x
    2.) x = 59.3 ft.

    Hope this helped.
