The ratio of the times taken by Dinesh and Edwin to cover a distance of 1000 km is 13:19. Find the ratio of their speeds.
19:13
For the same distance, speed is inversely proportional to time.
So the ratio of speeds is the reciprocal of the ratio of times.
Times are 13 : 19, so speeds of Dinesh and Edwin = 1/13 : 1/19 = 19 : 13.
Hence, 19:13.
