When trying to determine the speed of a car in an accident, police can use this formula:s = the square root of 24d The s is the speed of a car in miles per hour and the distance d is the feet that it skids on a dry road. How fast was a car going if it skidded 150 feet? Leave your solution in simplified form.
A. 40 mph
B. 50 mph
C. 60 mph
D. 70 mph

$$s=\sqrt{24d}$$
Put d=150 into the equation
$$s=\sqrt{24 \times 150}$$
$$s=\sqrt{3600}$$
Can you work out the answer?
