For a certain model of car the distance d required to stop the vehicle if it is traveling at v mi/h is given by the function
d(v) = v + \frac{v^{2}}{25}
where d is measured in feet. Kerry wants her stopping distance not to exceed 185 ft. At what range of speeds can she travel? (Assume v is positive. Round your values to one decimal place. Enter your answer using interval notation.)
