To find the speed of the pitch, we can use the formula: speed = distance/time.

First, we need to convert the distance from meters to kilometers, as the speed is usually measured in kilometers per hour (km/h). There are 1000 meters in 1 kilometer, so 85 meters is equal to 85/1000 = 0.085 kilometers.

Next, we need to convert the time from seconds to hours, as the speed is measured in km/h. There are 60 seconds in 1 minute, and 60 minutes in 1 hour. Therefore, 4 seconds is equal to 4/60/60 = 0.00111 hours.

Now, we can use the formula:

speed = distance/time

speed = 0.085 km / 0.00111 hours

Calculating this, we find that the speed of the pitch is approximately 76.58 km/h. Therefore, the pitch is traveling at a speed of approximately 76.58 kilometers per hour.
