Question

Собственная скорость лодки 25,8 км/ч, а скорость течения реки 1,7 км/ч. Лодка плыла по течению 2,3 ч, а против течения 1,5 ч. Найдите весь путь, пройденный лодкой.

Answer 1

1. Скорость лодки по течению = 25,8+1,7= 27,5 км/ч
2. Скорость лодки против течения = 25,8-1,7= 24,1 км/ч
Расстояние (1) = 27,5*2,3= 63,25 км
Расстояния (2) = 24,1*1,5= 36,15 км
Общее расстояние = 63,25+36,15= 99,4 км

Answer 2

Calculation of the Distance Traveled by the Boat

To calculate the total distance traveled by the boat, we need to consider the time spent traveling with the current and against the current separately.

Given information: - Boat's own speed: 25.8 km/h - Speed of the river's current: 1.7 km/h - Time spent traveling with the current: 2.3 hours - Time spent traveling against the current: 1.5 hours

To find the distance traveled with the current, we can use the formula:

Distance = Speed × Time

For the boat traveling with the current: - Speed = Boat's own speed + Speed of the river's current = 25.8 km/h + 1.7 km/h = 27.5 km/h - Time = 2.3 hours

Using the formula, we can calculate the
