15 км/ч

Пошаговое объяснение:

19,8 /2,2 = 9 км (разница часа езды велосипедиста и пешехода)

2,5 х = х +9

1,5 х = 9

х = 6

скорость пешехода 6 км/ч;

скорость велосипедиста 6 + 9 = 15 км/ч.

Ребят помогите пожалуйста!! Надо составить краткий пересказ этого текста (4-5 предложений) На английском!!

Have you ever wanted to achieve something really amazing in life? Well,Greg Mortenson wanted to climb a mountain, but he ended up helping thousands of people to have a better life!

Greg Mortenson's story began with faillure. In 1993, he set out to climb K2 , the world's second highest mountain. But Greg never made it to the top. After five days, he stembled into the village of Korphe in northern Pakistan, injured and hungry.

Greg saw that the villagers were very poor and there was a lot of disease and hunger.Also, the village school didn't have a roof and the children wrote on the ground with sticks. "I'll build you a school," he told the villagers. "I promise."

Greg went back home to the USA to raise money for the school. He even lived in his car to save money! But this was just the beginning of somothing much bigger! Since then, Greg's organisation has build around 80 schools and runs many others in Pakistan, Afghanistan and other countries, too.

Greg hasn't finished yet. He has won many humanitarian and peace awards, but it's the smiles of the children he has helped that makes him happy!

It's a thrilling read and proof of what ordinary people can do with courage and determination!
