A baseball pitcher throws a fastball at 51.6 m/s. If the batter is 18 m from the pitcher, approximately how much time does it take for the ball to reach the batter?

To calculate the time it takes for the ball to reach the batter, you can use the formula for time:

time = distance / speed

In this case, the distance is 18 m and the speed is 51.6 m/s. Plugging these values into the formula, we get:

time = 18 m / 51.6 m/s

To find the answer, simply divide 18 by 51.6:

time ≈ 0.349 seconds

So, it would take approximately 0.349 seconds for the ball to reach the batter.

d = rt

18 = (51.6)(t)
Solve for t.
