Given:

The maximum speed (v) that an automobile can travel around a curve of radius r without skidding is given by the equation:

[tex]v=(\frac{5r}{2})^{\frac{1}{2}}[/tex]

We will find the maximum speed v when r = 40 feet

so, substitute r = 40

[tex]v=(\frac{5*40}{2})^{\frac{1}{2}}=(100)^{\frac{1}{2}}=10[/tex]

So, the answer will be:

The car can travel up to 10 miles per hour.
