Answer:
 Team 3 Turtle, by 4 minutes
Step-by-step explanation:
The speeds of each of the turtles can be computed from ...
 speed = distance/time
Then for each of the turtles, the training pace is ...
 Team 1 Turtle: (18 ft)/(6 min) = 3 ft/min
 Team 2 Turtle: (12 ft)/(4 min) = 3 ft/min
 Team 3 Turtle: (10 ft)/(2 min) = 5 ft/min
The times required to cover the 30 ft distance at these paces are ...
 time = distance/speed
 3 ft/min ⇒ (30 ft)/(3 ft/min) = 10 min
 5 ft/min ⇒ (30 ft)/(5 ft/min) = 6 min
The 2nd-place finishers will take 10-6=4 minutes longer.
The expected winner is Team 3 Turtle by 4 minutes.
