Question
 M and N walk along a circular track. They start at
5:00 a.m. from the same point in the opposite directions. M and N walk at a speed of 5 rounds per hour and 2 rounds per hour, respectively. How many times will they cross each other before 6.30 a.m. on the same day?Solution
M and N start at 5:00 a.m. from the same point in opposite directions, with speeds of 5 and 2 rounds per hour, respectively. Since they move in opposite directions, their relative speed is (5 + 2 = 7) rounds per hour. They walk for 1.5 hours (from 5:00 to 6:30), covering a combined distance of (7 x 1.5 = 10.5) rounds. Since they cross each other once per round, the number of crossings is the whole part of 10.5, which is 10. Hence, they cross each other 10 times before 6:30 a.m.
