this is due today !!! please help me !
Question 1:
The formula v=√2.4r models the maximum safe speed, v, in miles per hour, at which a car can travel on a curved road with radius of curvature, r , in feet. A highway crew measures the radius of curvature at an exit ramp on a highway as 750 feet. What is the maximum safe speed?
For this problem, round your answer DOWN to the nearest whole number. (Think: Why is this type of rounding appropriate for this scenario?)
Question 2:
Police use the function V=√20L to estimate the speed of a car in miles per hour, based on the length, L , in feet, of its skid marks when suddenly braking on a dry, asphalt road.
Round your answers to the nearest tenth as needed
At the scene of an accident, a police officer measures a car's skid marks to be 110 feet long. Approximately how fast was the car traveling?
