A covers a certain distance at a certain speed. If he covers one- third of the distance in three time then the ratio of this speed to the original speed is:
Let the total distance be 12 km and speed be 12 km/hr Time taken to cover 12 km with the speed of 12 km/hr = 1 hr According to the question New distance = 12/3 = 4 km New time = 3 × 1 = 3 hrs New speed = 4/3 km/hr ∴ Ratio of new speed to original speed = 4/3:12 = 1:9
