Integer generally means number.
if s = seconds then
2s = 18
solve for s,
18/2 = 7
s = 7 seconds
Answer:
ball took 9 seconds to reach at the end o the ramp.
Step-by-step explanation:
Whitney rolls a ball down a ramp.
Length of the ramp = 18 feet
Speed by which the ball rolls down = 2 feet per second
Let the ball takes T seconds to reach the end of the ramp.
By the formula,
Time taken = [tex]\frac{\text{Distance rolled}}{\text{Speed}}[/tex]
= [tex]\frac{18}{2}[/tex]
= 9 seconds
Therefore, ball took 9 seconds to reach at the end o the ramp.
