15 км/ч  т.к. в 1 км = 1000 м , то 15 * 1000 = 15000 метров и в 1 часе = 60 минут, то 15000 : 60 = 250 метров/мин скорость одного лыжника и он бежит быстрее на 50 метров в час что = 50 : 1000 * 60 = 3 км/ч,  или 200 м/мин = 200 : 1000 * 60 = 12 км/ч, тогда
15 - 12 = 3 км/ч разница
на 3 км/ч пробегает больше первый лыжник
