Answer: The speed of red horse = 44 feet per second and the speed of black horse = 35.2 feet per second.
Step-by-step explanation:
Given: A red horse and a black horse raced on a 1-mile-long circular racetrack.
Time taken by red horse = 120 seconds
Time taken by black horse = 150 seconds
Speed = 
So, speed of red horse =
Since 1 mile = 5280 feet
Speed of red horse = 
Similarly,
Speed of black horse = 
Hence, the speed of red horse = 44 feet per second and the speed of black horse = 35.2 feet per second.
Use proportion to solve this.
240 miles needs 9 gallons
216 miles needs (9÷240) × 216 = 8.1 gallons
