Question

Какое растояние по течению пройдет моторная лодка за 4 часа если ее собственная скорость 13 км/ч,а скорость течения 2 км/ч ?

Answer 1

13+2=15 (км/ч) скорость катера по течению реки
15*4=60 (км) расстояние
Ответ 60 км пройдет катер по течению реки

Answer 2

Calculating the Distance Traveled by the Motorboat

To calculate the distance traveled by the motorboat, we can use the formula: Distance = Speed × Time

Given: - Motorboat's own speed = 13 km/h - Speed of the current = 2 km/h - Time = 4 hours

First, we need to calculate the effective speed of the motorboat, taking into account the speed of the current.

The effective speed of the motorboat can be calculated using the formula: Effective Speed = Motorboat's Speed + Speed of the Current

Substituting the given values: Effective Speed = 13 km/h + 2 km/h = 15 km/h

Now, we can calculate the distance traveled by the motorboat using the effective speed: Distance = Effective Speed × Time

Substituting the values: Distance = 15 km/h × 4 hours = 60 km

So, the motorboat will travel a distance of 60 kilometers downstream in 4 hours.
