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 +  v2 25 where d is measured in feet. Kerry wants her stopping distance not to exceed 180 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.)
