1. The time it will take for the car to skid for 150 feet is 8.23 seconds.

   How to find the time the car will skid?

   The function D(t) = 18t² − 130t gives the distance a car going a certain speed will skid in t seconds.

   The time the it would take for the car to skid for 150 feet can be calculated as follows:

   Therefore,

   D(t) = 18t² – 130t

   150 =  18t² – 130t

   18t² – 130t – 150 = 0

   divide by 3

   9t² – 65t – 75 = 0

   Hence,

   t = 65 ± 5√277 / 18

   t = 8.23425471586 or -1.01166666667

   Hence,

   t = 8.23 seconds.

   Therefore, the time it will take for the car to skid for 150 feet is 8.23 seconds.
