Question
A car travels a certain distance in 4 hours at a speed
of 60 km/h, then covers the remaining distance in 2 hours at a speed of 90 km/h. Find the total distance covered by the car.Solution
Let the total distance be D. In the first part of the journey, time = 4 hours and speed = 60 km/h. Distance covered = 60 × 4 = 240 km. Let the remaining distance be D - 240. In the second part, time = 2 hours and speed = 90 km/h. Distance covered = 90 × 2 = 180 km. Thus, D = 240 + 180 = 420 km.
