Rahul and Raghavare 110 km apart from each other and they started horse-riding towards each other at same time at a speed of 20 km/hr and 24 km/hr. After how many hours of riding will they be 22 km away from each other?
-
1 hour
-
1.5 hour
-
2 hour
-
2.5 hour
C
Correct answer
Explanation
Rahul and Raghav start 110 km apart and ride toward each other. Their relative speed is 20 + 24 = 44 km/hr. They need to cover 110 - 22 = 88 km to be 22 km apart. Time = distance / speed = 88/44 = 2 hours. Option C is correct. The key is finding relative speed and the distance they actually need to close.
