A turtle 2

A turtle can walk 1/12 of a kilometer in an hour. The turtle is 1/5 of a kilometer away from a pond.
How long will it take the turtle to reach the pond at this speed?

Correct answer:

t =  12/5 = 2 ²⁄₅ h
t₂ =  144 min

Step-by-step explanation:

$$\begin{gathered} v=\frac{1}{12}\doteq 0.0833\text{km/h} \\ s=\frac{1}{5}=0.2\text{km} \\ s=v\cdot t \\ t=s/v=\frac{1}{5}/\frac{1}{12}=\frac{1}{5}:\frac{1}{12}=\frac{1}{5}\cdot \frac{12}{1}=\frac{1\cdot 12}{5\cdot 1}=\frac{12}{5}=\frac{12}{5}\text{h}=2.4\text{h} \end{gathered}$$

$t_2=t\to \text{min}=t\cdot 60\text{min}=2.4\cdot 60\text{min}=144\text{min}=144\text{min}$
