Решите пожалуйста: Винни пух поднялся на дерево со скоростью 0,9 км/ч, затем 4 минуты ел из улья мед. Поев мед, он спустился вниз на воздушном шаре с постоянной скоростью 1,6 км/ч. Все время с начала момента подъема винни пуха под деревом бегал пяточок со скоростью 3,6 км/ч, делая через каждые несколько метров остановку на 5 секунд. В общей сложности пяточок останавливался 20 раз. Определите, сколько метров пробежал пяточок к моменту спуска винни пуха на землю, если известно, что это расстояние в 20,25 раз превышает высоту, на которую взбирался винни пух.
