Trip kilometers

The route of the tourist trip measures 28 cm on a map with a scale of 1:50000. The average walking speed is 4km/h.
How many kilometers does the trip measure?
How many hours will the students spend on the trip?

Final Answer:

s =  14 km
t =  3.5 h

Step-by-step explanation:

$$\begin{gathered} v=4\text{km/h} \\ M=50000 \\ {s}_1=28\text{cm}\to \text{km}=28:100000\text{km}=0.00028\text{km} \\ s=s_1\cdot M=0.0003\cdot 50000\text{km}=14\text{km} \end{gathered}$$

$t=s/v=14/4=\frac{7}{2}\text{h}=3.5\text{h}$
