Question

Скорость парохода в стоячей воде V км в час скорость течения реки равна N км в час За сколько времени пройдет пароход расстояние в M километрах двигаясь по течению реки

Answer 1

Время t:
Время = расстояние (M)/(собственная скорость+скорость течения((N))

t=M/(V+N)

Answer 2

Calculation of the Time Taken by a Steamboat to Travel a Distance in a River Current

To calculate the time taken by a steamboat to travel a distance in a river current, we need to consider the speed of the steamboat in still water (V km/h), the speed of the river current (N km/h), and the distance to be traveled (M kilometers).

The formula to calculate the time taken is:

Time = Distance / (Speed of Steamboat + Speed of River Current)

Let's use this formula to calculate the time taken.

Calculation Example

Let's assume the speed of the steamboat in still water (V) is 20 km/h, the speed of the river current (N) is 2 km/h, and the distance to be traveled (M) is 30 kilometers.

Using the formula, we can calculate the time taken as follows:

Time = 30 km / (20 km/h + 2 km/h)

Simplifying the equation:

Time = 30 km / 22 km/h

Calculating the result:

Time = 1.36 hours

Therefore, the steamboat will take approximately 1.36 hours to travel a distance of 30 kilometers while moving with the river current.

Please note that the actual time taken may vary depending on the specific conditions and factors involved.
