Question

Скорость движения лодки в в стоячей воде 3752м в час скорость течения реки 1976 м в час найдите скорость движения лодки по течению реки и против течения

Answer 1

По течению - 3752+1976=5548 м/чпротив течения - 3752-1976=1776 м/ч

Answer 2

 1)3752+1976=5548 м/ч-скорость лодки по течению
 2)3752-1976=1776 м/ч- скорость лодки против течения
Ответ:5548 м/ч скорость лодки по течению реки, 1776 м/ч скорость лодки против течения реки.

Answer 3

Calculating Boat Speed in Still Water, Current Speed, and Speed Against the Current

To find the speed of the boat in still water, the speed of the current, and the speed of the boat against the current, we can use the following formulas:

1. Speed of the Boat in Still Water (B): This is the speed of the boat when there is no current affecting its motion.

Formula: B = (Boat Speed + Current Speed) / 2

2. Speed of the Current (C): This is the speed of the water current.

Formula: C = (Boat Speed - Boat Speed in Current) / 2

3. Speed of the Boat Against the Current (B - C): This is the speed of the boat when it moves against the current.

Formula: B - C

Let's calculate these values using the given data.

Calculation

Given: - Speed of the boat in still water (B): 3752 m/h - Speed of the current (C): 1976 m/h

Using the formulas: 1. Speed of the Boat in Still Water (B): - B = (3752 + 1976) / 2 - B = 5728 / 2 - B = 2864 m/h

2. Speed of the Current (C): - C = (3752 - 1976) / 2 - C = 1776 / 2 - C = 888 m/h

3. Speed of the Boat Against the Current (B - C): - B - C = 2864 - 888 - B - C = 1976 m/h

Conclusion

The speed of the boat in still water is 2864 m/h, the speed of the current is 888 m/h, and the speed of the boat against the current is 1976 m/h.
