If the biker had averaged 25 kph, they would have finished the race 1 hour faster. What was the distance that the race covered? : Let d = distance of the race : Write a time equation, time = dist/speed : 15kmh time - 25kmh time = 1 hr - = 1 Multiply by 75 to clear the denominators, results 5d - 3d = 75 2d = 75 d = d = 37.5 km : : Check this by finding the time of each 37.5/15 = 2.5 hrs 37.5/25 = 1.5 hrs ----------------- Time diff: 1 hr
