Question

A rock climber averages $12\frac{3}{5}$ feet climbed per minute. How many feet does the rock climber climb in $30$ minutes. Justify your answer.

Answer 1

Find the distance which rock climber climb in $30$ minute.

Given : Average climb per minute $=12\frac{3}{5}=\frac{63}{5}$ feet.

Let the climber climb $\mathrm{x}$ feet in $30$ minutes.

We know that,

$\mathrm{Speed}=\frac{\mathrm{Distance}}{\mathrm{Time}}$

$$\begin{gathered} \Rightarrow \frac{63}{5}=\frac{\mathrm{x}}{30} \\ \Rightarrow \frac{63\times 30}{5}=\mathrm{x} \\ \Rightarrow \mathrm{x}=378 \end{gathered}$$

Hence, the rock climber will climb $378$ feet in $30$ minutes.
