Средняя скорость велосипедиста на всем пути равна 40км/ч .Первую половину пути он ехал со скоростью 60 км/ч.С какой скоростью велосипедист проехал остаток пути?

Ответы

Автор ответа: stassemenec

по идее 20км/час как то так

Автор ответа: olhovikstas

Смотри: 60-на 20 больше, чем 40, тогда надовго 40-20, и ты узнаешь скорость на второй половине пути, а далее чтобы проверить правильный ли ответ сделай так:(20+60)розделить на 2, так как мы прибавляли два числа между собой. В итоге мы получили 40, а значит ответ правильный
