The longest Brazilian river, the Amazon, is ten times longer than the two Czech rivers, Vltava and Berounka. The ratio of the lengths of the Vltava and Berounka is 9:5. At the same time, the length ratio of the Vltava and Morava rivers is 5:4. How many kilometers does the Amazon flow if we know that Moravia is 360 km long?

Correct answer:

a =  7000 km

Step-by-step explanation:

m=360 km v:b=9:5 v:m = 5:4  v=m 45=360 45=4360 5=41800=450 km  b=v 95=450 95=9450 5=92250=250 km  a=10 (v+b)=10 (450+250)=7000 km
