Ответ:

№3 5км/мин или 300км/ч №4 ≈13.3 м/сек

Объяснение:

скорость = расстояние / время

ilyaiut: в 1 задаче 50км делишь на 10 минут, затем переводишь в км/час если надо

ilyaiut: во второй время переводишь в секунды , 1 минута = 60 секунд. 60+52.5 =112.5, затем делешь 1500 м на 112.5 и переводишь в нужную единицу измерения если надо
