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 β10xβ km is 2 hour less than time taken by the bus to cover a distance of β5xβ km, then find the value of β10xβSolution
According to the question, (5x/6) β (10x/30) = 2 Or, (5x Γ 5 β 10x Γ 1) Γ· 30 = 2 Or, (25x β 10x) Γ· 30 = 2 So, x = 4 Required value = 10 Γ 4 = 40
The sky appears blue because of β
