Question
A car starts with a speed of 90 km/h, with its speed
increasing every 2 hours by 10 km/h. In how many hours will it cover 479 km?Solution
Distance covered in the first 2 hours = (90 x 2) km = 180 km Distance covered in the next 2 hours = (100 x 2) km = 200 km Remaining distance = 479 - (180 + 200) = 99 km Now, speed in the fifth hour = 110 km/hr ∴ Time taken to cover 99 km = 99/110 = 9/10 hrs ∴ Total time taken = 2 + 2 + 9/10 = 4 + 9/10 = 4hrs 54 min
