Question

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 1

Integer generally means number.

if s = seconds then

2s = 18

solve for s,

18/2 = 7

s = 7 seconds

Answer 2

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 = $\frac{\text{Distance rolled}}{\text{Speed}}$

                   = $\frac{18}{2}$

                   = 9 seconds

Therefore, ball took 9 seconds to reach at the end o the ramp.
