Question

Плот, отправленный от пристани А, через 6 часов до пристани Б. Расстояние между пристанями равно 12 км. За какое время моторная лодка от пристани Б дойдет до пристани А, если собственная скорость лодки 6 км/ч?

Answer 1

12:6=2км/ч скорость течения
6-2=4км/ч скорость лодки против течения
12:4=3ч -время за которое моторная лодка дойдет от Б до А

Answer 2

Calculating Time for Motorboat to Reach Port A from Port B

To calculate the time it takes for the motorboat to reach Port A from Port B, we can use the formula:

Time = Distance / Speed

Given: - Distance between the ports = 12 km - Speed of the motorboat = 6 km/h

Using the formula, we can calculate the time it takes for the motorboat to reach Port A from Port B.

Calculation

Time = 12 km / 6 km/h

Time = 2 hours

Therefore, the motorboat will take 2 hours to reach Port A from Port B at a speed of 6 km/h.

This calculation is based on the given distance and speed, and it does not take into account external factors such as currents or wind.
