Six friends

Six friends who live inland decide to take a road trip to the closest beach, which is 661 1/2 kilometers away. They decided to share the driving equally. How many kilometers will each person have to drive

Correct answer:

x =  110 ¹⁄₄ = 441/4 km

Step-by-step explanation:

$$\begin{gathered} a=661\frac{1}{2}=661+\frac{1}{2}=\frac{661\cdot 2+1}{2}=\frac{1322+1}{2}=\frac{1323}{2}=661.5\text{km} \\ n=6 \\ x=a/n=\frac{1323}{2}/6=\frac{1323}{2\cdot 6}=\frac{1323}{12}=\frac{441}{4}\text{km}=110\frac{1}{4}\text{km}=110.25\text{km} \end{gathered}$$
