Question

ПОМОГИТЕ Собственная скорость лодки равна 4 км/ч, а скорость течения реки равна 1,5 км/ч. С какой скоростью будет двигаться лодка против течения реки?

Answer 1

4-1.5=2.5км/ч......................

Answer 2

 Собственная скорость = 4 км/ч
Скорость течения = 1,5 км/ч

4-1,5= 2,5 км/ч
Ответ: скорость лодки против течения реки  2,5 км/ч.

Answer 3

Calculating the Boat's Speed Against the River Current

To calculate the speed of the boat against the river current, we can use the formula: boat's speed against the current = boat's speed - river's speed.

Given: - Boat's speed = 4 km/h- River's speed = 1.5 km/h Using the formula, we can calculate the boat's speed against the river current as follows:

Boat's speed against the current = 4 km/h - 1.5 km/h = 2.5 km/h.

Therefore, the boat will move against the river current at a speed of 2.5 km/h.
