Question
Anshul lives on 20th floor and Keshav lives on 57th
floor. Anshul goes up at a rate of 36 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 = 57 – 20 = 37 floors Relative speed = 36 + 38 = 74 floor/min Time taken by them to meet = total floors/relative speed = 37/74 = 1/2 min Anshul travels in 1/2 min = 1/2 x 36 = 18 floors Floor at which Anshul and Keshav will meet = 20 + 18 = 38th floor
