Answer:
The speed of the car traveling was 45.8 miles/hour
Step-by-step explanation:
* Lets explain how to solve the problem
- A police accident investigator can use the formula S = 2√(5L) to
estimate the speed S of a car in miles per hour based on the length
L in feet of the skid marks it left
- To calculate the speed of a car traveling that left skid marks 105 feet
long substitute L by 105
∵ S = 2√(5L)
∵ L = 105 feet
∴ S = 2√(5 × 105) = 2√(525)
∴ S = 45.8 miles/hour
* The speed of the car traveling that left skid marks 105 feet long
was 45.8 miles/hour
