A truck left the village for the city. After 3 hours, a bus left the city to meet the truck. The truck traveled a distance of 355 km to the meeting in 5 hours. The distance between the city and the village is 515 km. How much is the bus speed faster than the truck?

1) 355: 5 = 71 (km / h) – truck speed
2) 5 – 3 = 2 (h) – the bus was traveling until the meeting
3) 515 – 355 = 160 (km) – the bus drove to the meeting
4) 160: 2 = 80 (km / h) – bus speed
5) 80 – 71 = 9 (km / h) – difference
Answer: at 9 km / h
