Question
Speed of a car and a bus is 20 km/h and 12 km/h,
respectively. If the time taken by the car to cover a distance of ‘5x’ km is 1 hour less than time taken by the bus to cover a distance of ‘6x’ km, then find the value of ‘5x’Solution
According to the question, (6x/12) – (5x/20) = 1 Or, (6x × 5 – 5x × 3) ÷ 60 = 1 Or, (30x – 15x) ÷ 60 = 1 So, x = 4 Required value = 5 × 4 = 20
