Question
Anshul lives on 16th floor and Keshav lives on 49th
floor. Anshul goes up at a rate of 28 floors per minute and Keshav comes down at a rate of 38 floors per minute. At which floor they will meet?ÂSolution
Total floors between Anshul and Keshav = 49 – 16 = 33 floors Relative speed = 28 + 38 = 66 floor/min Time taken by them to meet = total floors/relative speed = 33/66 = 1/2 min Anshul travels in 1/2 min = 1/2 x 28 = 14 floors Floor at which Anshul and Keshav will meet = 14 + 16 = 30th floor
