The straight

The straight path rises by 72 cm every 3 m of its length. How many meters will it climb to 350 m?

Correct answer:

h₂ =  84 m

Step-by-step explanation:

$$\begin{gathered} x_1=3\text{ m } \\ {h}_1=72\text{ cm}\to \text{ m}=72\mathrm{/}100\text{ m}=0.72\text{ m } \\ {x}_2=350\text{ m } \\ {x}_1:h_1=x_2:h_2 \\ {h}_2=h_1\cdot {\displaystyle \frac{x_2}{x_1}}=0.72\cdot {\displaystyle \frac{350}{3}}=84\text{ m} \end{gathered}$$
