If one and one-half teams of men require one and one-half days to shovel one and one-half truckloads of sand, how long will it take one team to shovel one truckload?

one day?

1 team needs 1.5*1.5 = 2.25 days to do 1.5 trucks

so 1 team needs 1.5 days to do one truck

To solve this problem, we need to break it down step by step. Let's start by identifying the given information and what we need to find:

Given:
- One and one-half teams of men
- One and one-half days
- One and one-half truckloads of sand

To find:
- How long will it take one team to shovel one truckload

We can use the information given to set up a ratio and solve for the unknown quantity.

Step 1: Start by setting up a ratio using the information given:
- (1.5 teams of men) : (1.5 days) = (1.5 truckloads of sand) : (unknown time for one team to shovel one truckload)

Step 2: Simplify the ratio by dividing all quantities by the common factor of 1.5:
- 1 team of men : 1 day = 1 truckload of sand : (unknown time for one team to shovel one truckload)

Step 3: From the simplified ratio, we can conclude that if 1 team of men can shovel 1 truckload of sand in 1 day, then it will take 1 team to shovel 1 truckload.

Therefore, the answer is one day.

So, it will take one team to shovel one truckload in one day.
