It is given that, a mouse covered a distance of 3/24 miles over a distance of 3 hours. Each hour, the mouse traveled the same distance. Distance traveled in 1 hour can be calculated by dividing 3/24 miles by 3. So,
Matt calculations shows that the distance is 3/8 hours. While dividing 3/24 by 3, he doesn't take reciprocal of 3 as a result he get 9 on numerator and 24 on denominator. Simplified fraction of 9/24 is 3/8. But the correct answer should be 1/24 hours.

There are two triangles so:
Multiply this by 13.25 to get total cost:
=$259.65
Ignoring the "?" in your question:
If the "?" is a squared symbol that wasn't caught:
Use the quadratic formula
to get the solutions:
as you can see, the discriminant is negative, so the equation has no solution.
