Question

Петя решил пойти в поход в лес. Он рассчитал себе маршрут, который составлял 16км(туда и обратно). Он вышел из дома и уже через 2 часа оказался в лесу. На пути обратно домой он решил не торопиться и насладиться красивыми пейзажами, но при этом прогулка обошлась в 2 раза дольше по времени. С какой скоростью Петя шёл из дома в лес и обратно?

Answer 1

Ответ: туда - 4км/ч; обратно 2км/ч.

Пошаговое объяснение:

16:2=8 (км) - в одну сторону.

8:2=4 (км/ч) - скорость ходьбы в лес.

2×2=4 (ч) - шёл из леса.

8:4=2 (км/ч) - скорость ходьбы обратно.

Answer 2

Відповідь:

Покрокове пояснення:

В лес он шёл 4км/час

Домой он шёл 2км/час

Answer 3

Calculation of Petya's Walking Speed

To calculate Petya's walking speed from home to the forest and back, we need to consider the distance he covered and the time it took him.

Petya planned a route that was 16 km long, including the distance to the forest and back. He left home and arrived in the forest after 2 hours. On his way back, he decided to take his time and enjoy the beautiful landscapes, resulting in the walk taking twice as long as the initial journey.

To find Petya's walking speed, we can use the formula:

Speed = Distance / Time

Let's calculate Petya's walking speed step by step:

1. Distance: Petya's route was 16 km long, including the distance to the forest and back.

2. Time: Petya took 2 hours to reach the forest.

3. Return Time: Since the return journey took twice as long, it would be 4 hours.

Now, let's calculate Petya's walking speed:

Speed from home to the forest: Speed = Distance / Time Speed = 16 km / 2 hours Speed = 8 km/h

Speed from the forest back to home: Speed = Distance / Time Speed = 16 km / 4 hours Speed = 4 km/h

Therefore, Petya walked from home to the forest at a speed of 8 km/h and from the forest back to home at a speed of 4 km/h.

Please note that these calculations are based on the information provided and assume a constant walking speed throughout the journey.
