Зная скорость и время мы можем найти, сколько проползет жук за 5сек.

S=V*t=6 см/с*5 с=30 см-проползет жук за 5сек.,далее мы знаем, что через 5 сек расстояние между жуком и гусеницей будет 100см, а было 60см, значит 100см-60см=40см-изменение расстояния за 5сек. Мы узнали, что жук прополз 30см, следовательно 40см-30см=10см-проползет гусеница за 5сек.Значит мы можем найти скорость гусеницы V=S/t=10см/5с=2 см/с

ответ: 5 см/с скорость гусеницы.
