Question

собственная скорость теплохода равна 23,8км/ч,скорость течения реки-1,6км/ч.найти скорость теплохода против течения и его скорости по тичению реки.

Answer 1

Скорость теплохода 23,8  км/ч

Скорость течения реки 1/6 км/ч

23,8-1,6=22,2 (км/ч скорость теплохода против течения реки)

23,8+1,6=25,4 (км/ч скорость теплохода по течению реки)

Answer 2

Calculation of the Speed of the Boat Against the Current

To find the speed of the boat against the current, we need to subtract the speed of the current from the speed of the boat.

Given: - Speed of the boat (own speed): 23.8 km/h - Speed of the current: 1.6 km/h

To calculate the speed of the boat against the current, we subtract the speed of the current from the speed of the boat:

Speed of the boat against the current = Speed of the boat - Speed of the current

Substituting the given values:

Speed of the boat against the current = 23.8 km/h - 1.6 km/h

Speed of the boat against the current = 22.2 km/h.

Calculation of the Speed of the Boat with the Current

To find the speed of the boat with the current, we need to add the speed of the current to the speed of the boat.

Given: - Speed of the boat (own speed): 23.8 km/h - Speed of the current: 1.6 km/h

To calculate the speed of the boat with the current, we add the speed of the current to the speed of the boat:

Speed of the boat with the current = Speed of the boat + Speed of the current

Substituting the given values:

Speed of the boat with the current = 23.8 km/h + 1.6 km/h

Speed of the boat with the current = 25.4 km/h.

Therefore, the speed of the boat against the current is 22.2 km/h, and the speed of the boat with the current is 25.4 km/h.
