In 5 minutes the turtle travelled = \(\frac{1}{30}\) of mile
Therefore in 60 minutes the turtle travelled = \({\frac{1}{(30 * 5)}} * 60 = 0.4 miles/hr\)

Explanation
The turtle traveled \(\frac{1}{30}\)of a mile (D) in 5 minutes (t), which is \(\frac{1}{12}\)of an hour. Using the D = RT formula, solve for r:
\(\frac{1}{30}=\frac{1}{12} r\)
0.4 = r
