The speed, s, that the vehicle was traveling in miles per hour can be approximated by the formula s=square root 30df, where d represents the length of the skid marks in fee and "f" represents the drag factor of the road. A vehicle that was involved in an accident on an asphalt road was traveling at a speed of 45 mph when it started skidding. If the drag factor for asphalt is 0.75 find the length of the skid marks made by the car. The skid marks made by the car were approximately___________ feet long. </span>

<span>s=square root 30df, where d represents the length of the skid marks in feet and "f" represents the drag factor of the road. A vehicle that was involved in an accident on an asphalt road was traveling at a speed of 45 mph when it started skidding. If the drag factor for asphalt is 0.75 find the length of the skid marks made by the car.
S = sqrt(30df)
45 = sqrt(30*d*0.75)
----
45 = sqrt[(90/4)d]
-----
45 = (3/2)sqrt(10d)
30 = sqrt(10d)
10d = 900
d = 90 ft.

You would do 45 divided by 9 which is 5. Then you do 5x7= 35 and that's your answer
Answer: Add all the numbers together which equals 55, then divide by how many numbers there are (5) so the answer is 11
