Marcus, a pitcher, throws a ball to home plate at 50 m/s. If home plate is 8 meters from the pitcher's mound. How many seconds does it take the ball to reach the catcher?

Question

The equation for average speed is:
Average speed = distance traveled / time
If we multiply both sides by time we get the equation for distance traveled given average speed and time:
Distance traveled = (average speed) x (time)
If we then divide that by average speed, we get the equation for time given average speed and distance traveled:
(distance traveled) / (average speed) = time
The average speed is 50 m/s
The distance traveled is 8 meters
If we plug in the numbers we get:
Time = 8m / 50 m/s = 0.16 seconds
