When police measure the length of a skid mark made by a car involved in an accident on a nearby road the police determine the speed s of the car (in mph) by the following equation: 
where d is the length of the skid mark in feet. What was the speed of the car when the length of the skid mark was 125 feet? Round to two decimal places.
Definitions:
Type I Errors
