Correct Answer: Option B
Explanation
The tiger takes 5 leaps per minute and the deer takes 4 leaps per minute. The speed of the tiger can be calculated using the formula speed = number of leaps per minute x distance covered per leap, which gives us speed = 5 leaps/minute x 8 meters/leap = 40 meters/minute. The speed of the deer can be calculated using the formula speed = number of leaps per minute x distance covered per leap, which gives us speed = 4 leaps/minute x 5 meters/leap = 20 meters/minute. The tiger is 50 leaps behind the deer, which is equivalent to a distance of 50 leaps x 8 meters/leap = 400 meters. The relative speed of the tiger and deer is given as 20 meters/minute. The time taken by the tiger to catch the deer can be calculated using the formula time = distance / speed, which gives us time = 400 meters / 20 meters/minute = 20 minutes. The distance traveled by the tiger before it catches the deer can be calculated using the formula distance = speed x time, which gives us distance = 40 meters/minute x 20 minutes = 800 meters.
