Vinil7 [7]

Answer:

2.4 miles

Step-by-step explanation:

This is a simple ratio problem.

Penguins go 4/5 mile in 1/3rd hour. So how many miles will they go in 1 hour? Let that be x:

$\frac{\frac{4}{5}}{\frac{1}{3}}=\frac{x}{1}\\\frac{1}{3}x=\frac{4}{5}\\x=\frac{4}{5}*3=\frac{12}{5}$

That is 12/5 miles or 2 2/5 miles

In decimal, that's 2.4 miles
