The top speed of a CraigCat boat is 32.24 miles per hour.

#### Work Step by Step

We need to convert 52 kilometers per hour to miles per hour. To do that, we multiply 52 by the ratio that converts kilometers to miles. The ratio that converts kilometers to miles is $\frac{0.62\ mile}{1\ kilometer}$. So,$\frac{52\ kilometers}{hour}$ $\times$ $\frac{0.62\ mile}{1\ kilometer}$ = $\frac{52 \times 0.62\ miles}{hour}$ = 32.24 miles per hour.
