For this case we have the following functions:

We must find
. By definition we have to:

So:

Finally, the composite function is:

Answer:

To change a degree measure to a radian measure, we multiply by (π/180). So 360° becomes 2π radians, and 240° becomes 4π/3.
To solve for the distance the car is required to stop after the driver
steps on the break is by jus substituting the given value to the equation
given. Since the car is traveling at 50 miles per hour
24d = (50)^2
D = 2500/24
<span>D =104 ft</span>
