A child builds two wooden train sets. The path of one of the trains can be represented by the function y = 2cos²x, where y represents the distance of the train from the child as a function of x minutes. The distance from the child to the second train can be represented by the function y = 3 + cos x. What is the number of minutes it will take until the two trains are first equidistant from the child? a b C d 6 minutes n minutes 1 minute 1.5 minutes
