A construction site needs 48 people to excavate and transport soil. Each person excavates 5 cubic meters of soil every day and transports 3 cubic meters of soil. How to arrange personnel to transport soil in time
Set X people to dig
5X=3(48-X)
5X=144-3X
8X=144
X=18
18 people dig the soil, 30 people transport the soil in time
When a farm is building water conservancy, 48 people are sent to complete the work of digging and transporting soil. If each person digs 5 cubic meters of soil or transports 3 cubic meters of soil on average every day, how to allocate the number of people to dig and transport soil so that the excavated soil can be transported away in time?
Let x excavate soil and Y transport soil. Then x + y = 485x = 3Y, the solution is x = 18y = 30. Answer: 18 excavate soil and 30 transport soil
There are 32 people in a small peasant team. They are taking part in the construction of water conservancy projects
If you are the team leader, you are going to arrange () people to dig and () people to transport the soil, so as to ensure that the excavated soil can be cleared away
If I am the team leader, you are going to arrange (12) people to dig and (20) people to transport the soil, so as to ensure that the excavated soil can be cleared away
