Question

If a car skids to a stop over the distance of 80 feet, find the speed of the car. Use the formula, s= square root of 24d where s = speed and d =distance. Round your answer to the nearest whole number.

Answer 1

43

Answer 2

\[s=\sqrt{24*d}\]
if d = to 'skid distance' in feet
\[s=\sqrt{24*90}=\sqrt{1920}=43.8\]
