Question

сёмга сначала плыла 3 ч со скоростью 38 км/ч а потом она проплыла ещё 2 ч С какой средней скоростью проплывёт сёмга оставшийся путь если все она проплыла 194 км

Answer 1

1)194 - (3х38):2=40(км/ч)

Ответ:со скоростью 40 км/ч  проплывёт сёмга оставшийся путь.

 

Answer 2

Calculation of Average Speed

To calculate the average speed of the salmon, we can use the formula:

Average Speed = Total Distance / Total Time

Given the information provided, let's calculate the average speed of the salmon.

1. The salmon initially swam for 3 hours at a speed of 38 km/h. 2. Then, the salmon swam for an additional 2 hours.

To find the average speed, we need to determine the total distance covered by the salmon.

The total distance covered by the salmon can be calculated by adding the distance covered in the first 3 hours to the distance covered in the next 2 hours.

Let's calculate the distance covered in the first 3 hours:

Distance = Speed × Time

Distance = 38 km/h × 3 hours = 114 km

Now, let's calculate the distance covered in the next 2 hours:

Distance = Speed × Time

Distance = ? km/h × 2 hours

Unfortunately, the specific speed during the next 2 hours is not provided in the question. Therefore, we cannot calculate the exact average speed or the remaining distance covered by the salmon.
