Чтобы найти среднюю скорость нужно весь пройденный путь разделить на всё затраченное время.107,2+30,8=138км.(весь путь)5+4=9часов.(Всё время)138:9=15,3км/ч.(если округлить , то 15 км/ч)Ответ:15,3км/ч.(15км/ч)

Sebastian and his dog Kellie were close friends. Kellie thought Sebastian was the kindest boy in the world. Sebastian thought Kellie was the smartest dog in the world. Sebastian wrote a short poem about his pet Kellie.
Funny, pretty, loving,
Naughty, kind and brave,
Friendly, clever, noisy,
Playing night and day!
Sebastian’s mum thought they got on well with each other. They were the most loving family in the world. Kellie could play all kinds of different games with Sebastian and could bring in magazines and newspapers from the letterbox to his mum every day.
Kellie and Sebastian went together everywhere. She could carry Sebastian’s bag to school. She waited when the lessons were over and Sebastian came out. After school they visited Sebastian’s mum at work. She worked in the cafe near their house.
One day they saw a robbery. It was in front of mum’s cafe. A robber pushed Mrs Clifford, took her bag and ran off.
Poor Mrs Clifford was left lying on the ground with her eyes closed. Mum and other people rushed to help her. Nobody saw the robber except for Sebastian and Kellie.
“After him, Kellie!” said Sebastian. They followed the robber down Royal Street and into Cardiff Road. They didn’t get too close. But they could see Mrs Clifford’s bag inside his jacket.
Halfway along Sainsbury Street the robber stopped and looked around.
“Let’s walk and play, Kellie!” Sebastian told Kellie. Behind him, the robber saw just a small boy walking with his big dog.
“We only want to see where he goes. We don’t want to catch him,” said Sebastian.
Before number ten the robber stopped, opened the door and went inside.
“Got it! Number 10 Sainsbury Street,” said Sebastian.
He opened his school bag, took out a sheet of paper, wrote a note and gave it to Kellie.
“I’ll stay here and watch for him. You go for help, Kellie. Give the note to Mum. Go!” he said.
