The ratio of the speed of car to that of a train is
15:22. If the speed of the train is 35 Km/hr more than that of the car, what is the speed of the car?Solution
Let the speed of car and train be 15x & 22x respectively. According to the question, 22 x - 15x = 35 ⇒ 7x = 35 ⇒ x = 5km/hr ∴ Speed of the car = 15x = 15 × 5 = 75 km/hr.
