Решение: Пусть на теплоходе проехал х км, тогда на поезде проехал (х+120) км, если бы вна поезде проехал бы в 4 раза больше, то на поезде бы проехал 4*(х+120)=4х+480 км, если бы на теплоходе проехал в 8 раз больше, то на теплоходе бы проехал 8х км, по условию задачи составляем уравнение:

4х+480+8х=1200

решаем его

12х+480=1200

12х=1200-480

12х=720

х=72012

х=60

Следовательно на теплоходе проехал 60 км

Ответ: 60 км

One day, Melanie, a nurse at an animal hospital, found six tiny kittens. Their

mother was nowhere to be seen.

Melanie took the kittens home. She thought her pet cat would look after them.

Instead, she got a big surprise. Her cat wasn't interested in the kittens. And the

"It's amazing. They climb all over her and look to get milk from her. Summer just
