 A building has installed 5 colored lights to welcome the 2010 Asian Games in Guangzhou. The sequence in which they shine is not fixed, and each light can only shine in one of the colors: red, orange, yellow, green, or blue, with each of the 5 lights shining in a different color. Let's define the ordered shining of these 5 lights once as one "flash". In each flash, only one light shines per second, and the interval between two consecutive flashes is 5 seconds. Calculate the minimum time required to achieve all different flashes. Express your answer in seconds. Show your work in <think> </think> tags. And return the final answer in <answer> </answer> tags.<|im_end|>
