Question
Speed of a car and a bus is 25 km/h and 15 km/h,
respectively. If the time taken by the car to cover a distance of β8xβ km is 1 hour less than time taken by the bus to cover a distance of β6xβ km, then find the value of β8xβ.Solution
According to the question, (6x/15) β (8x/25) = 1 Or, (6x Γ 5 β 8x Γ 3) Γ· 75 = 1 Or, (30x β 24x) Γ· 75 = 1 So, x = 12.5 Required value = 8 Γ 12.5 = 100
