To find the approximate speed of the vehicle, we can plug in the given skid mark length into the formula and solve for speed:

0.75d = 30.25
0.75(150) = 30.25
112.5 = 30.25
s = 112.5 / 0.75
s = 150

Therefore, the approximate speed of the vehicle was about 67 miles per hour.

Therefore, the correct answer is:
- about 67 miles per hour
