Question
Ramesh covered one-fourth of the total journey at 30
km/h and the rest at 45 km/h. If he took a total of 8 hours to complete the journey, how much distance did he travel at 45 km/h?Solution
ATQ,
Let the total distance be 4D km. ATQ: (D/30) + (3D/45) = 8 Or, (3D + 6D) ÷ 90 = 8 Or, (9D/90) = 8 So, D = 80 Required distance = 3 × 80 = 240 km
