Question 1047134: A cyclist to travel to 20 km/h faster than an in-line skater. In the time it took the cycle is to travel 80 km of the skater had gone 30 km. find the speed of the skater
Answer by jorel555(1290) (Show Source): You can put this solution on YOUR website!
Let n be the speed of the skater. Then:
80/(n+20)=30/n
80n=30n+600
n=12 km/h as the speed of the skater; 32 km/h as the speed of the cyclist. ☺☺☺☺
