Question

Задаса по физики. скорость зайца 15м\с, а скорость дельфина 18км\ч. кто из них быстрей

Answer 1

18км/ч=1800:6=300м/с. Дельфин быстрее.

Answer 2

Comparison of Speeds: Rabbit vs. Dolphin

The speed of the rabbit is 15 m/s and the speed of the dolphin is 18 km/h. To determine which one is faster, we need to convert the speed of the dolphin from kilometers per hour to meters per second for a fair comparison.

Conversion of Dolphin's Speed from km/h to m/s

To convert the speed of the dolphin from kilometers per hour to meters per second, we can use the following conversion factor: 1 km/h = 0.277778 m/s.

Converting the speed of the dolphin: 18 km/h * 0.277778 m/s = 5 m/s.

Conclusion

Comparing the speeds, we find that the dolphin is faster, with a speed of 5 m/s, compared to the rabbit's speed of 15 m/s.
