Question
Speed of a car and a bus is 30 km/h and 6 km/h,
respectively. If the time taken by the car to cover a distance of ‘10x’ km is 2 hour less than time taken by the bus to cover a distance of ‘5x’ km, then find the value of ‘10x’Solution
According to the question, (5x/6) – (10x/30) = 2 Or, (5x × 5 – 10x × 1) ÷ 30 = 2 Or, (25x – 10x) ÷ 30 = 2 So, x = 4 Required value = 10 × 4 = 40
