пароход простоял на мели 3 часа, потому что он прошел до остановки 96 км, а потом еще 24 км, а катер прошел 24+96=120 км, т.е. катер проплыл 120/15=8 ч, делаем 8 ч- 5 ч=3 ч

A London Fog

It is a very foggy day in London. The fog is so thick that it is impossible to see more than a foot or so. Buses, cars and taxis are not able to run and are standing by the side of the road. People are trying to find their way about on foot but are losing their way in the fog. Mr. Smith has a very important meeting at the House of Commons and has to get there but no one can take him. He tries to walk there but finds he is quite lost. Suddenly he bumps into a stranger. The stranger asks if he can help him. Mr. Smith says he wants to get to the Houses of Parliament. The stranger tells him he will take him there. Mr. Smith thanks him and they start to walk there. The dog is getting thicker every minute but the stranger has no difficulty in finding the way. He goes along one street, turns down another, crosses a square and at last after about half an hour’s walk they arrive at the Houses of Parliament. Mr. Smith can’t understand how the stranger finds his way. “ It is wonderful,” he says . “ How do you find the way in this fog?”
“ It is no trouble at all to me,” says the stranger. “ I am blind.”
