On Saturday, Justin drove 52 miles per hour for three hours. How far did he go?

As shown in the figure, Isaiah's track forms a right triangle. Hence, we can apply the pythagorean theorem.

First, we find the hypotenuse or the longest side of the right triangle. The equation is: c^2 = a^2 + b^2, where c is hypotenuse, whereas a and b are the two shorter legs.

c = √(0.75^2 +1.2^2) = 1.415 miles

Therefore, the total distance is 1.415 + 0.75 + 1.2 = 3.37 miles
