4. The circumference of the front wheel is $1.1 \mathrm{~m}$, and that of the rear wheel is $0.8 \mathrm{~m}$. How far have we traveled if the front wheel made 69 fewer revolutions than the rear wheel? Round the result to the nearest centimeter. Use the approximation $\frac{22}{7}$ for $\pi$. Write down the answer.
4. For one revolution we transport $o=2 \pi r$ ..... 1 point
With the front wheel we transport $x \cdot 1.1 \pi$ ..... 1 point
With the rear wheel we transport $(x+69) \cdot 0.8 \pi$ ..... 1 point
The equation written is $x \cdot 1.1 \pi=(x+69) \cdot 0.8 \pi$ ..... 1 point
Calculated $x=184$ ..... 1 point
Solution and written answer: $o=636.11 \mathrm{~m}$ ..... 1 point
Note: If the result is not correctly rounded, the contestant does not receive the last point.
