A construction site sends 96 people to excavate and transport soil. If each person excavates 5m cubic meters of soil or transports 3M cubic meters of soil every day, how to allocate the number of people to excavate and transport soil A construction site sends 8 people to dig and transport soil. If each person digs 5m cubic meters of soil or transports 3M cubic meters of soil every day, how to allocate the number of people to dig and transport soil so that the excavated soil can just be transported? linear equation in two unknowns The first question is the wrong number
Set X people to dig soil and 8-x people to transport soil
5X=(8-X)*3
X=3
The number of people carrying soil is 8-3 = 5
Three men dug the earth
How to allocate the number of people who dig and transport soil
Work efficiency 5:3
The number of people is 3:5
The number of diggers is 80x3 / (5 + 3) = 30
Soil transportation 80-30 = 50 people
A construction site sends 96 people to excavate and transport soil. If each person excavates 5M3 soil or transports 3m3 soil per day, how to allocate the number of people to excavate and transport soil so that the excavated soil can be transported away in time?
According to the meaning of the title: x + y = 965x = 3Y, the solution is: x = 36Y = 60. A: there are 36 people digging and 60 people transporting, so that the excavated soil is just transported away in time
