Solve the Problem $\mathrm { v } = \sqrt { 2.5 \mathrm { r } }$

Multiple Choice

Solve the problem.
-The formula $\mathrm { v } = \sqrt { 2.5 \mathrm { r } }$ can be used to estimate the maximum safe velocity $\mathrm { v }$ , 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.

A) $490 \mathrm { ft }$
B) $3063 \mathrm { ft }$
C) $196 \mathrm { ft }$
D) $1225 \mathrm { ft }$
