When calculating the division, Xiao Chun wrote the divisor 72 as 27, and the result showed that the quotient was 26 and the remaining 18. What is the correct quotient?

When calculating the division, Xiao Chun wrote the divisor 72 as 27, and the result showed that the quotient was 26 and the remaining 18. What is the correct quotient?

The correct divisor is 27 * 26 + 18 = 720
The correct quotient is 720 / 72 = 10

Mathematics problems in grade one of junior high school
Party A and Party B are 6km apart. They start at the same time and walk in opposite directions. They meet in one hour and start at the same time and walk in the same direction. They can catch up with Party B in three hours. What's the average speed of the two characters? (what's the formula)
There is a section of uphill road and a section of level road from a to B. if the uphill road is 3km per hour, the level road is 4km per hour, and the downhill road is 5km per hour, then it takes 54 minutes from a to B and 42 minutes from B to A. what is the whole journey from a to B?

1. Let the velocity of a be x and B be y, and set up the equations x + y = 6, 3x = 3y-6, so x = 2, y = 42. The flat road from a to B is the same as that from B to a, but the difference is that a to B is uphill and B to a is downhill. The uphill speed is 3km / h and the downhill speed is 5km / h
