Question

Папа с Янисом шли на рыбалку к озеру 7 мин со скоростью 60м/мин и увеличив скорость на 8 м/мин шли до озера ещё 12 мин определи расстояние от дома до озера

Answer 1

1) 7*60=420 (м)-прошли папа с Янисом сначала
2) 60+8=68 (м/мин)-скорость, которую они увеличили
3) 68*12=816 (м)-шли, когда увеличили скорость
4) 420+816=1236 (м)
Ответ: 1236 метров, расстояние от дома до озера

Answer 2

Calculation of Distance from Home to the Lake

To calculate the distance from home to the lake, we need to determine the total distance traveled during the fishing trip.

According to the information provided, the father and Janis walked to the lake for 7 minutes at a speed of 60 m/min. Then, they increased their speed by 8 m/min and continued walking for another 12 minutes.

To calculate the distance, we can use the formula:

Distance = Speed × Time

Let's calculate the distance for each part of the trip and then add them together to find the total distance.

1. Distance covered in the first part of the trip (7 minutes at a speed of 60 m/min):

Distance 1 = Speed × Time = 60 m/min × 7 min = 420 meters.

2. Distance covered in the second part of the trip (12 minutes at a speed of 60 m/min + 8 m/min):

Distance 2 = Speed × Time = (60 m/min + 8 m/min) × 12 min = 816 meters.

Now, let's calculate the total distance:

Total Distance = Distance 1 + Distance 2 = 420 meters + 816 meters = 1236 meters

Therefore, the distance from home to the lake is approximately 1236 meters.

Please note that the above calculation assumes a constant speed throughout the trip and does not take into account any changes in direction or terrain.
