Question

Кто поможет очень срочно надо вот краткая запись: t по течению = 2,5 ч ; t против течения = 0.8 ч ; V собственная скорость катера = 40 км/ч ; V скорость течения = 2,2 км/ч ; S-? ПОМОГИТЕ ПОЖАЛУЙСТАААА

Answer 1

Путь по течению= (40+2.2)*2.5=105.5 км
Путь против течения=(40-2.2)*0.8=30.24 км 
Общий путь 105.5+30.24=135.74 км

Answer 2

Calculation of Distance Traveled

To calculate the distance traveled, we can use the formula:

Distance = (Speed of the boat + Speed of the current) × Time

Given the following values: - Speed of the boat (V собственная скорость катера) = 40 km/h - Speed of the current (V скорость течения) = 2.2 km/h - Time with the current (t по течению) = 2.5 hours - Time against the current (t против течения) = 0.8 hours

Let's calculate the distance traveled in each scenario.

1. Distance traveled with the current: - Speed = (40 km/h + 2.2 km/h) = 42.2 km/h - Time = 2.5 hours - Distance = Speed × Time = 42.2 km/h × 2.5 hours = 105.5 km

2. Distance traveled against the current: - Speed = (40 km/h - 2.2 km/h) = 37.8 km/h - Time = 0.8 hours - Distance = Speed × Time = 37.8 km/h × 0.8 hours = 30.24 km

Therefore, the distance traveled with the current is 105.5 km and the distance traveled against the current is 30.24 km.
