For route ‘X’: Let the speed of Amit for 2 hours be ‘a’ km/hr Therefore, total distance covered = 2a + 1.2a = 3.2a km For route ‘Y’: Speed of Amit for 2 hours = 0.8a km/hr Therefore, total distance covered = 0.8a × 2 + 1.25 × 0.8a = 2.6a km According to the question, 3.2a – 2.6a = 15 Or, a = 15/0.6 = 25 Therefore, distance of the longer route = 3.2a = 80 km
