Ответ:

скорость такси 98 км/час

поскольку такси ехало 4 часа, проехало расстояние 392 км

так как поезд проехал 300 км 60км/час*5 часов=300 км

автобус проехал 144 км

72км/час*2 часа=144 км

2 часа потому, что вдвое меньше чем на такси

836-300+144=392

4 часа/392 км=98 км/час-скорость такси

Task 1
The King and the Painter

Once there was a king, who liked to paint pictures, but his

pictures were bad and nobody liked them. The people to whom the king showed his pictures were afraid of him and they said that the pictures were good. One day the king showed his pictures to a great painter who lived in that country and said, “What do you think of my pictures? Am I a good painter or not?” The painter looked at the king’s picture and said, “My king, the pictures are bad and you will never be a good painter.” The king was very angry and sent the painter to prison. After two years the king wanted to see the painter again. When the painter came the king gave him a good dinner and said, “Now you are a freeman and I am your friend.” So he talked kindly to the painter.
