Question

1. Катер плыл по озеру 4 часа со скоростью 39 км/ч., а затем 5 часов вверх по течению со скоростью 42 км/ч. Какой путь проплыл катер?​

Answer 1

Ответ:

366

Пошаговое объяснение:

1) 39x4=156 (км) проплыл катер по озеру.

2)42x5=210 (км) Ехал катер по течению.

3)210+156=366 (км)

Ответ: 366 км проехал катер.

Answer 2

Calculation of the Distance Traveled by the Boat

To calculate the distance traveled by the boat, we need to find the sum of the distances covered during the two different segments of the journey.

1. Distance covered in the first segment: - The boat traveled for 4 hours at a speed of 39 km/h. - Using the formula distance = speed × time, we can calculate the distance covered in this segment as follows: - Distance = 39 km/h × 4 hours = 156 km.

2. Distance covered in the second segment: - The boat traveled for 5 hours against the current at a speed of 42 km/h. - Again, using the formula distance = speed × time, we can calculate the distance covered in this segment as follows: - Distance = 42 km/h × 5 hours = 210 km.

3. Total distance traveled by the boat: - To find the total distance traveled by the boat, we need to add the distances covered in the two segments: - Total distance = Distance in the first segment + Distance in the second segment - Total distance = 156 km + 210 km = 366 km.

Therefore, the boat traveled a total distance of 366 km.
