Question 1174201: The formula v = sq. rt. 2.5r, can be used to estimate the maximum safe velocity v, in miles per hour, at which a car can travel along a curved road with a radius of curvature r, in feet. To the nearest whole number, find the radius of curvature if the maximum safe velocity is 35 miles per hour.

.

The equation is


    v = .


Square both sides 


    v^2 = 2.5r


and express "r"


    r = .


Now substitute v = 35 mph to the formula (1) and compute the radius.


At the end, round properly.
