Прозвенел звонок с последнего урока, и ученики устремились в
столовую. Пошёл туда и учитель. Ученики проголодались сильнее и прибежали в
столовую быстрее. В этот момент учитель прошел 80 метров. Но учеников без учителя
кормить не стали, и они побежали назад. Когда они встретились с учителем, он прошел
ещё 16 метров. Определите расстояние (в метрах) от класса до столовой?-

V1 - скорость учениковV2 - скорость учителяS - путь от класса до столовойS/V1=80/V2(S-(80+16))/V1=16/V2S/V1-96/V1=16/V280/V2-16/V2=96/V164/V2=96/V12/V2=3/V12V1=3V2=> скорость учеников в 1,5раза больше, чем учителя и пробежали они путь до столовой в полтора длиннее, чем учитель.S=80*1,5=120м
