Question
A car travels 240 km in 4 hours. After 2 hours, it
increases its speed by 20 km/h and covers the remaining distance in 1 hour. What is the speed of the car in the first 2 hours?Solution
Let the speed of the car in the first 2 hours be x km/h. Distance traveled in the first 2 hours = 2x After 2 hours, the car increases its speed by 20 km/h. The speed during the next 1 hour = (x + 20) km/h. Distance traveled in the next hour = (x + 20) km. The remaining distance is covered in the last hour, so 2x + (x + 20) = 240 km 3x + 20 = 240 3x = 220 x = 220 / 3 = 73.33 km/h Correct Option: c) 73.33 km/h
