Question 15
A fox sees a rabbit grazing 21 meters from his place. In one second, the rabbit was able to run 5 steps while the fox only 3 steps. It is also known that the distance travelled by the fox in 4 steps will take the rabbit 9 steps to completely cover. If the distance travelled by the rabbit in every step is 0.6 meter, how many seconds will it take the fox to catch the rabbit?
