Question

Собственная скорость лодки равна 14 километров в час двигаясь против течения реки лодка за 3 часа удалилась от. пристани на 36 километров Найдите скорость течения реки

Answer 1

1)14км×3ч=42км. ( на столько км удалилась бы лодка в стоячей воде). 2)42км-36км=6 км. 3)6км:3ч=2 км(скорость течения реки)

Answer 2

Calculation of River Current Speed

To find the speed of the river current, we can use the formula:

Boat's Speed - River Current Speed = Distance / Time

Given that the boat's speed is 14 kilometers per hour and it took 3 hours for the boat to travel a distance of 36 kilometers against the current, we can substitute these values into the formula:

14 - River Current Speed = 36 / 3

Simplifying the equation:

14 - River Current Speed = 12

To find the speed of the river current, we subtract 12 from both sides of the equation:

River Current Speed = 14 - 12 = 2 kilometers per hour

Therefore, the speed of the river current is 2 kilometers per hour.
