Xiaoli's family of three traveled from Beijing to Guangzhou. The railway between Beijing and Guangzhou is 2294 kilometers long. The average speed of the train 1 1 km has been exercised.

Brother. . The average speed of your train should be 1 10 km! When did the train speed reach 10 km? )

According to the timetable, there is no such train in reality, so it is only a mathematical problem.

According to the speed formula, the train has traveled 1980 km. With 2294- 1980=3 14, it can be known that the train probably traveled to the south of Shi Ping Town, Lechang, Shaoguan City, Guangzhou.

I left at 8 pm and ran for 18 hours. It was already 2 pm the next day. . . According to the speed of 1 10, the remaining 3 14 kilometers will take less than 3 hours, that is, it will arrive in Guangzhou around 5 o'clock.
