Ответ:

1. Так как туристы шли в противоположных направлениях, найдем скорость их отдаления, сложив их скорости:

4 + 5 = 9 км/ч.

2. Определим, какое расстояние будет между ними через 5 часов, умножив их суммарную скорость на 5 ч:

9 * 5 = 45 км.

Ответ: через 5 часов туристы будут в 45 км друг от друга.

2.

14+12=26км/ч(общая скорость)

78:26=3ч(они проедут всего три часа)

14*3=42км(проедет один велосипедист)

12*3=36км(проедет второй велосипедист)

"And little Richard said, "Okay, daddy. I love to sing, so maybe I'll become a singer. I'll go in a circle to sing and learn! "And it was a wonderful day. All day he and his friends sang and laughed. "I'm going to become a singer, I'm sure." said little Richard to his parents that day. And they smiled. The next day the teacher came to class. All day he talked about nature, plants and animals, and he told the children how to care for nature. In the evening Richard told his parents: "I want to join in the study of nature in the circle now. I don't want to be more than a singer. I want to be a scientist! "And the parents smiled. On Friday, little Richard went to the pool. "Water is great! he exclaimed.
