Question

Акула проплывает за 2 мин. расстояние 1 км, а заяц бежит со скоростью 60 км/ч. Кто из них движется быстрее?Во сколько раз? 1)акула в 1.5 раза 2) акула в 2.2 раза 3)заяц в 2 раза 4)движутся одинаково

Answer 1

1) 2 мин.= 2/60 часа = 1/30  часа
1 :  1/30 = 1/1  *  30/1 = 30  км/ч - скорость акулы
2) 60 км/ч : 30 км/ч = 2 (раза)   быстрее заяц , чем акула

ОТВЕТ:  3) заяц в 2 раза .

Answer 2

Answer:

The shark swims a distance of 1 km in 2 minutes, while the hare runs at a speed of 60 km/h. To determine who is moving faster and by how much, we can calculate the distance covered by the hare in 2 minutes and compare it with the distance covered by the shark in the same time.

Calculation:

- Distance covered by the hare in 2 minutes: - Speed of the hare = 60 km/h - Time = 2 minutes = 2/60 hours - Distance = Speed × Time = 60 × (2/60) = 2 km

Comparison:

- The shark covers 1 km in 2 minutes, while the hare covers 2 km in the same time. - Therefore, the hare moves faster than the shark. - The hare moves twice as fast as the shark.

This comparison shows that the hare is moving faster than the shark and is covering twice the distance in the same time.

I hope this helps! If you have any other questions, feel free to ask.
