Traffic engineers study how long the yellow light for a traffic signal should be. For one intersection, the number of seconds n required for a yellow light is related to the average approach speed v, in feet per second, by the following. +100 n = 1 20 If the approach speed is 95 feet per second (about 65 miles per hour), how long should the yellow light be?
