the womens 4 by 100 meter medley relay swimming team finished in second place. In the relay, each member swims 100 meters using a different swimming stroke. The names and ages of the team members are jenny,19, annie,20 asia,22, and destiny,39.
The age difference between the oldest and youngest swimmer on this team is 20 years. Suppose they had broken up the distance of 400 meters by age. how far would each person swim in the relay?

broken up how? If the distance swum is proportional to the age, then since the sum of the ages is 100,
Jenny would swim 19/100 of the 400m, or 19*4=76m
Annie: 20/100 * 400 = 80m
and so on
