Let the speed be x from place A to place Bby party a, then the speed when B returns to A is x+10, and we can get the equation 15x =151*x+10. The solution will get x=5. The distance between B and B is 15*5=75km. Let the distance between B and B is X kilometers. If the distance between B and B is X kilometers, we get X15=X15110, then X=75 kilometers. Therefore, if the distance between B and B is 75 kilometers, let the distance between the two places is X kilometers, and the speed when driving is y, then we have Xy=by party a; Only A takes the shortest time, so it takes time for A to send the flashlight back and forth =2+1+5+1+10+1=20 minutes, where 1 is the analysis of the time for A to return.
Assuming the amount of this document is X, it is known that A completes X10 every hour, and B completes X12 every hour, so a total of X10+X12*3 was completed in the first 3 hours, leaving XX10+X12*3= 065X. Finally, A completes the document, so 065X X10=65 hours.by party aYou can also set the number of documents as 1, the speed of A as 110 per hour, and the speed of B as 112 per; the Chinese characters hidden in Shen Zi include the following: 1. Statement ~ Ming ~ Please 2. The ninth digit of the earth branch 3. Shen Shi, the old timekeeping method, equivalent to 15:00 to 17:00 4. Another name of Shanghai City is 2.

If you learn the equation, you can set this pile of coal as 2s. A takes x days and B takes y days. From the meaning of the question, we can see that 7x +2y =1x +1y4 can get x= 3y2. If the two transportation teams of A and B can jointly transport it in 8 days, it can be completed. Therefore, there is 1x +1y8 =2s, so 2s= 403y, so the time required for B is 2sy=403 hours. The time required for A is x= 3y2, that is, 20 hours.
