Question

The lengths of the river Parana and Paraguay are in the ratio 5:3. The Parana is 2500 miles long. How long is the Paraguay?

Answer 1

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
