Answer:
1500 miles
Step-by-step explanation:
Given data
We are given that the ratio of the length of river Parana and Paraguay is
5:3
Parana is 2500 miles
Applying then part to part approach
let the length of Paraguay be x
5/3= 2500/x
cross multiply we have
5*x= 2500*3
5x= 7500
divide both sides by 5
x= 7500/5
x=1500 miles
Hence the lenght is 1500 miles
