A bus, a car from a to start, a minibus from B to a. the speed is 42km / h, 60km / h, 48km / h respectively. The minibus meets the bus half an hour after meeting the car, and the distance between a and B is calculated

Half an hour is 30 minutes, that is, 0.5 hours. The distance between the minibus and the bus is (42 + 48) × 0.5 = 45km, that is to say, the minibus travels 45km more than the bus, and the speed of the minibus travels 60-42 = 18km more than the bus. Therefore, the time taken for the minibus to meet the minibus is 4

Honghong's mother bought some apples. If every three apples are put on a plate, there will be one left. If every four apples are put on a plate, there will be one left. If every five apples are put on a plate, there will be one left. How many apples does Honghong's mother buy at least

3. The least common multiple of 4 and 5 = 3 × 4 × 5 = 60, at least the number of apples bought is 60 + 1 = 61. A: Honghong's mother bought at least 61 apples

Please don't solve it in the form of equation
There is a story book. You can read the same few stories every day for 20 days. If you read three more stories every day, you can finish them three days in advance. How many stories are there

Sorry, it was too fast just now. There was a problem with the calculation. I'm sorry,
I finished reading it three days in advance, which means that I actually watched it for 17 days, because I watched more than three sections every day, and I watched more than 17 days
3 * (20-3) = 51 segments
What we should watch more is actually the number of paragraphs we should watch in the next three days. We used to watch every day
51 / 3 = 17
altogether:
17 * 20 = 340 section
