How many kilometers will the boat pass in 3 hours, moving along the river, the speed of which is 1400 m / h and this is 4/30 (this is a fraction 4 numerator, and the denominator is 30) of the boat’s own speed?

Let’s find the value of the own speed of this boat, for this we need to divide the value of the river flow speed by the specified fraction:

1400: 4/30 = 10500 m / h – this is the value of the boat’s own speed;

Let’s find the value of the speed along the river flow of the given boat, for this we need the value of the own speed of the given boat, add the value of the speed of the river flow:

10500 + 1400 = 11900 km / h – this is the value of the speed along the river for this boat;

Let’s find the distance that the given boat will cover in the specified time, for this we need to multiply the speed value along the river flow of the given boat by the specified time:

11900 * 3 = 35700 m / h – this is the distance this boat will cover in 3 hours.

Answer: 35700 m / h – this is the distance this boat will cover in 3 hours.
