Лодка плывёт по течению реки. Гребец уронил в воду шляпу и, не заметив этого, продолжал плыть дальше. Какое расстояние будет между лодкой и шляпой через 10 мин, если собственная скорость лодки - 9 км/ч.

х км/ч - скорость течения (скорость движ. шляпы)

(9+х) км/ч - скорость лодки по течению

9+х-х=9(км/ч) - скорость отставания шляпы от лодки в 1 час

10мин=1/6часа

S=V*t

9*1/6=1,5(км) - будет расстояние между лодкой и шляпой через 10минут

Floods are disasters that often happen all over the world. They occur when a river overflows its banks because of an unusually high water level. Floods rare- ly catch people by surprise because they usually hap- pen after a heavy rainstorm or after the sudden melt- ing of snow in spring or in summer. In most cases there is enough time for people to leave their homes. As floods often occur in the country, they can destroy fields, kill animals and wash away cars. But after the warning farmers usually move their animals and cars to higher ground. In dangerous areas where floods occur rather often, people can build up the riverbanks with sandbags to limit the amount of water that will overflow. Sometimes, however, a river can rise higher and faster than expected. When this happens, emergency workers arrive to help. They monitor the water level and warn people to leave their houses. They do this by broadcasting messages on the radio or by warning people in person. Some people prefer not to leave their houses. They climb onto the roofs of their houses to escape the water and wait there to be rescued. Using helicopters and boats emergency workers pick the people and domestic animals up and take them to evacuation camps on higher ground. A terrible flood happened in Sochi in 2015 because of severe rainstorms in the mountains. Lots of houses were washed away into the Black Sea. Fortu- nately people were warned in time and escaped before the high water reached their houses. After the emergency had passed, the emergeney workers cleared away all the rubbish on the roads and examined bridges and electricity. They also put up special warning signs for drivers on the damaged roads​
