Question 761011: The formula v = sq. rt. 2.5r, models the safe maximum speed, v, in mph, at which a car can travel on a curved road with a radius of curvature, r, in feet. A highway crew measures the radius of curvature at an exit ramp as 640 ft. What is the maximum safe speed?
Please show how to do this. Thank you so much.

formula: v =
Using r = 640
v =
v =
v = 40mph
This is the maximum safety speed.
Hope this helps.
