Let the speeds of Ajay and Vishal be 3x and 2x km/hr respectively. Distance covered by Vishal in 72 seconds = 2x x (5/18) x 72 = 40x m Distance covered by Ajay in 42 seconds = 3x x (5/18) x 42 = 35x m According to the question, => 40x – 35x = 40 => x = 8 Therefore the speed of Vishal = 2x = 16 km/hr
