в 3 раза, как решать не знаю.)                                        

Answer 3

Calculation of Speed Difference

To calculate the speed difference between Sonya and her brother Alyosha, we need to compare the distances they cover in the same amount of time. Sonya takes 12 minutes to walk from home to school, while Alyosha runs to school and back in 8 minutes.

Let's assume that the distance from home to school is the same for both Sonya and Alyosha. Since Alyosha covers this distance twice (to school and back), we can say that Alyosha covers the same distance as Sonya in half the time.

Therefore, Alyosha's speed is twice as fast as Sonya's speed.

Conclusion

Alyosha's speed is twice as fast as Sonya's speed.
