Question
Speed of a car and a bus is 26 km/h and 10 km/h,
respectively. If the time taken by the car to cover a distance of ‘8x’ km is 1 hour less than time taken by the bus to cover a distance of ‘5x’ km, then find the value of ‘8x’Solution
According to the question, (5x/10) – (8x/26) = 1 Or, (5x × 13 – 8x × 5) ÷ 130 = 1 Or, (65x – 40x) ÷ 130 = 1 So, x = 5.2 Required value = 8 × 5.2 = 41.6
