Question
Speed of a car and a bus is 20 km/h and 10 km/h,
respectively. If the time taken by the car to cover a distance of ‘9x’ km is 4 hour less than time taken by the bus to cover a distance of ‘5x’ km, then find the value of ‘9x’Solution
According to the question, (5x/10) – (9x/20) = 4 Or, (5x × 2 – 9x × 1) ÷ 20 = 4 Or, (10x – 9x) ÷ 20 = 4 So, x = 80 Required value = 9 × 80 = 720
