Where:

is the car's velocity

is the distance the winner car traveled

is the time

Isolating :

Solving with the given information:

This is the winner's time

step-by-step explanation:

hypotenuse = √(15² + 8²)

=  √(225 +64)

=  √(289) = 17

sin(x) = cos(y) = 8/17

they are identical so long as you are doing the sine of one angle and the cosine of the only other angle that isn't the right angle.
