Jeníček will go on vacation with his parents and go by boat for a certain part of the journey. He is interested in how many nautical miles they will sail if their route represents by a line 7.4 cm long on a 1:25,000 scale map. (1 nautical mile = 1,850 m)

Correct answer:

x =  1 nm

Step-by-step explanation:

$$\begin{gathered} M=25000 \\ a=7.4\text{cm}\to \text{m}=7.4:100\text{m}=0.074\text{m} \\ m=1850\text{m} \\ b=a\cdot M=0.074\cdot 25000=1850\text{m} \\ x=b/m=1850/1850=1\text{nm} \end{gathered}$$
