2. whitney rolls a ball down a ramp that is 18 feet long. if the ball rolls down 2 feet each second, what integer represents the amount of time, in seconds, the ball takes to reach the end of the ramp?
Answer
Explanation:
Step1: Identify the relevant information
The ramp is 18 feet long and the ball rolls 2 feet each second.
Step2: Use the formula for time - distance - speed
We know that time (t=\frac{d}{s}), where (d) is distance and (s) is speed. Here, (d = 18) feet and (s=2) feet per second. [t=\frac{18}{2}]
Step3: Calculate the time
(t = 9) seconds
Answer:
9
