Question

Скорость моторной лодки по течению 37 километров в час скорость течения реки 3 километров час Какое расстояние проплывет моторная лодка против течения за 2 часа

Answer 1

37-3=34(км/ч) - собственная скорость лодки
34-3=31(км/ч) - скорость против течения
31*2=62(км) - проплывет лодка против течения за 2 часа
Ответ: 62 км

Answer 2

Calculation of Distance Traveled by the Motorboat

To calculate the distance traveled by the motorboat against the current, we need to consider the speed of the motorboat and the speed of the river current.

Given: - Speed of the motorboat in still water: 37 kilometers per hour - Speed of the river current: 3 kilometers per hour - Time: 2 hours

To calculate the distance traveled by the motorboat against the current, we can subtract the speed of the river current from the speed of the motorboat and then multiply the resulting speed by the time.

The speed of the motorboat against the current can be calculated as follows: Speed against the current = Speed of the motorboat - Speed of the river current

Substituting the given values: Speed against the current = 37 km/h - 3 km/h = 34 km/h.

Now, we can calculate the distance traveled by the motorboat against the current using the formula: Distance = Speed × Time

Substituting the values: Distance = 34 km/h × 2 hours = 68 kilometers

Therefore, the motorboat will travel a distance of 68 kilometers against the current in 2 hours.

Please note that the above calculation assumes a constant speed and direction of the river current throughout the journey.
