Chalet

The children were on a school trip to the mountain. One-third of the journey went by train and continued by bus. When you get off the bus, they remain a third of the distance they traveled by bus. What part of the journey do children go by bus (write as a decimal and as a fraction)?

Correct answer:

x =  0.5

Step-by-step explanation:

$$\begin{gathered} \frac{s}{3}+x\cdot s+\frac{s}{3}=s \\ 1/3+x+x/3=1 \\ 4x=2 \\ x=\frac{2}{4}=0.5 \\ x=\frac{1}{2}=0.5 \end{gathered}$$
