Ответ:

1) Г). Но если они летят идеально с одинаковой скоростью в одно и тоже время, то В), однако в жизни такое маловероятно.

2) Переводим км/ч в м/с, для этого делим на 3,6. 10,8 разделить на 3,6 будет 3 м/с. получается что Катя быстрее, теперь делим скорость Кати на скорость Пети и получаем два, значит Катя быстрее в два раза.

3) 1. Да, так как время идёт а скорость одна и та же

2. 332 м/с

3. Плохо сфоткал, если там написано за время 3 секунды, то:

S= V*t = 332 * 3 = 996 метров
