Anshul lives on 18th floor and Keshav lives on 53th
floor. Anshul goes up at a rate of 34 floors per minute and Keshav comes down at a rate of 36 floors per minute. At which floor they will meet?ÂSolution
Total floors between Anshul and Keshav = 53 – 18 = 35 floors Relative speed = 34 + 36 = 70 floor/min Time taken by them to meet = total floors/relative speed = 35/70 = 1/2 min Anshul travels in 1/2 min = 1/2 x 34 = 17 floors Floor at which Anshul and Keshav will meet = 18 + 17 = 35th floor
