Answer:
The price of 1km of pipe is $175
Step-by-step explanation:
First, we have the price per 40cm of pipe, then we should see how much times we can fit 40cm into one kilometer.
First write both magnitudes in the same units:
40cm = 0.4m
1km = 1000m
Then we see the quotient:
1km/40cm = 1000m/0.4m = 2500
So we can divide a 1km pipe into 2500 40cm pipes.
Knowing that 40cm of pipe are priced at 7cm, then 2500 times that is:
2500*175
The price of 1km of pipe is $175
