An accident investigator is documenting a scene where a vehicle left skid marks on the pavement. To estimate the vehicle's speed ($s$) in miles per hour based on the distance of the skid marks ($d$) in feet, which of the following formulas must the investigator recall?

An accident investigator is preparing a report and needs to estimate a vehicle's speed ($s$) based on skid marks found at the scene. Using the formula $s = \sqrt{24d}$, arrange the following steps in the correct order to calculate the speed as shown in the textbook example.

An accident reconstruction specialist uses the formula $s = \sqrt{24d}$ to estimate how fast a vehicle was traveling before the driver applied the brakes. Based on the textbook example, match each component of this formula or its units with the correct description.

An accident reconstruction specialist is training a new investigator to use the standard speed formula $s = \sqrt{24d}$. Following the established example where the skid marks measure 190 feet, the investigator should recall that the estimated speed is approximately ____ miles per hour (rounded to one decimal place).

Rounding Convention in the Skid Mark Example

An accident reconstruction trainee is reviewing a case study involving a vehicle that left a 190-foot skid mark. According to the speed formula $s = \sqrt{24d}$, substituting $d = 190$ yields an intermediate value under the radical of 4560, which simplifies and rounds to an estimated pre-braking speed of approximately 67.5 miles per hour.
