Answer:
30 ways
Step-by-step explanation:
The first medal can be awarded in 6 different ways since any of the runners could have it. Once the first medal is awarded, the second medal can only be given to any of the 5 runners available.
So there are 6x5=30 different ways to award the medals
Ratio 9:13:18......added = 40. This means that one person gets 9/40 of the total, one person gets 13/40 of the total and one person gets 18/40 of the total.
and if the total is 800...
9/40 * 800 = 7200/40 = 180 <==
13/40 * 800 = 10400/40 = 260 <==
18/40 * 800 = 14400/40 = 360 <==
