The new water supply pipeline is to be 1.2 km long. Employees put it from both ends. On one side, 0.492 km of pipeline is laid, and on the other side, 53,500 cm of a pipeline. How many meters of pipe are left to lay?

Correct answer:

x =  173 m

Step-by-step explanation:

$$\begin{gathered} a=1.2\text{km}\to \text{m}=1.2\cdot 1000\text{m}=1200\text{m} \\ b=0.492\text{km}\to \text{m}=0.492\cdot 1000\text{m}=492\text{m} \\ c=53500\text{cm}\to \text{m}=53500:100\text{m}=535\text{m} \\ x=a-b-c=1200-492-535=173\text{m} \end{gathered}$$
