A dog saw a cat at a distance of 280 m. The cat started running at the speed of 10 km/hr and the dog also ran to catch it with the speed of 24 km/hr. How much time will the dog take to catch the cat?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is Option 3 i.e.1.2 min.
The distance between dog and cat = 280m
Relative speed = 24 - 10 = 14 km/h × 5/18 = 35/9 m/s
Time taken the dog take to catch the cat = 280/(35/9) = 72 Sec = 1.2 min
