Answer: the turtle won the race by 0.5 minutes.
Explanation:
The total distance to be covered by either the turtle or the rabbit is 100 feet.
The turtle travels at a constant speed of 20 feet per minute for the entire 100 feet.
Time = distance/speed
It means that the time taken by the turtle to travel 100 feet would be
100/20 = 5 minutes
The rabbit travels at a constant speed of 40 feet per minute for the first 50 feet. This means that the time taken by the rabbit to travel 40 feet would be
50/40 = 1.25 minutes.
It stopped and rested for 3 minutes. Therefore,
Total time spent already is 3 + 0.08 = 3.08 minutes
It then continues at a constant speed of 40 feet per minute for the last 50 feet. This means that the time taken by the rabbit to travel 40 feet would be
50/40 = 1.25 minutes.
Total time spent by the the Rabbit is 1.25 + 1.25 + 3 = 5.5 minutes
Difference between their times is
5.5 - 5 = 0.5 minutes
