Question

The Amazon River, one of the
longest rivers in the world, is about 6,400 kilometers long. If 1 mile equals 1.6 kilometers, what is the length of the Amazon River in miles?

Answer 1

Answer:

4000 miles.

Step-by-step explanation:

Divide 6400 by 1.6 to get 4000

Answer 2

Answer:

If we know each miles are 1.6 km, we can do a rule of three to get the length of the river:

1    1.6

X   6400

Now, we know that  = 4000 miles

You can also just divide 6400/ 1.6 as each 1.6 kilometers are one mile
