The equation that can be used to determine the time for each leg is D. 600t = 480(18 – t)
<h3>How to calculate the equation?</h3>
Speed on going ,= 600 miles per hour.
Speed on return = 480 miles per hour
Time on returning = 18 - t
Distance = Speed × Time
Distance = 480(18 - t)
The equation that can be used to determine the time for each leg will be:
600t = 480(18 – t)

Answer:
24 Tennis balls
Step-by-step explanation:
Calculation for How many tennis balls are left
First step
Since we have 12 can with 3 balls each Let the number of balls that the tennis pro has at the beginning be x
x=(12 can ×3 balls each)
x=36
Second step
Since we have 4 players who lost 3 ball each Let the total number of balls that was lost be y
y=(4 players×3 balls each)
y=12
Third step is to calculate How many tennis balls are left
Since x represent the number of balls at the beginning and y represent the number of balls that was lost , then let the number of tennis balls that was left after the session represent z
z=36−12
z=24 Tennis balls
Therefore the numbers of tennis balls that are left will be 24 Tennis balls
