1. How many cubes of 1 cubic meter can be cut? If the cubes are arranged in a row, how long is it 2. On the map with a scale of 1:4000000, it is measured that the distance between a and B is 28cm. A train runs 280km at 4 hours. According to this calculation, the train leaves from a at 10:20 a.m. and arrives at B at what time in the morning the next day? 3. Uncle Wang parked his car in the parking lot at 11:30 a.m. and paid 14.50 yuan. The fee for receiving manuscripts: 9.50 yuan for one hour, and 2.50 yuan for every 0.5 hour for more than one hour.

Answer: 1.1 m = 10 decimeters; can cut 10 * 10 = 100 small cubes of 1 cubic decimeter
2. The distance between Party A and Party B is 28 * 4000000 = 112000000 cm = 1120 km; the train speed is 280 / 4 = 70 km / h, and the time from place a to place B is 1120 / 70 = 16 hours. The train leaves from place a at 10:20 a.m. and arrives at 2:20 a.m. the next day
3.1 hours pay 9.50 yuan, pay 14.50-9.50 = 5 yuan more, because more than 1 hour, pay 0.50 yuan every 0.5 hours, the excess time is 5 / 2.5 = 2, that is, more than 2 0.5 hours, a total of 1 hour, Uncle Wang parking time = 1 + 1 = 2 hours, the car left at 13:30
