Question

Власна швидкість човна 16,2 км/год, а швидкість течії річки 1,5 км/год. Яку відстань пройде човен проти течії за 2,5 год?Срочно с объяснением действий​

Answer 1

Выражение: (16,2 - 1,5) · 2,5 = 36,75.

1) 16,2 - 1,5 = 14,7 км/ч - скорость лодки против течения реки;

2) 14,7 · 2,5 = 36,75 км - расстояние, которое проплывёт лодка за 2,5 ч против течения реки.

Ответ: 36 км 750 м.

Answer 2

Ответ:

36.75км или 36 км 750 м

1) 16.2-1.5=14.7(км/ч) - скорость против течения

2)14.7*2.5=36.75(км) - пройдет лодка против течения

Answer 3

Calculating Distance Traveled Against the Current

To calculate the distance the boat will travel against the current, we can use the formula:

Distance = Speed of the boat - Speed of the current

Given: - Speed of the boat (B) = 16.2 km/h - Speed of the current (C) = 1.5 km/h - Time taken (T) = 2.5 hours

Calculation Steps

1. Calculate the effective speed of the boat against the current: - The effective speed of the boat against the current is the difference between the speed of the boat and the speed of the current. - Effective Speed = Speed of the boat - Speed of the current - Effective Speed = 16.2 km/h - 1.5 km/h - Effective Speed = 14.7 km/h

2. Calculate the distance traveled: - Now that we have the effective speed, we can calculate the distance traveled using the formula: - Distance = Effective Speed × Time - Distance = 14.7 km/h × 2.5 h - Distance = 36.75 km

Answer

The boat will travel a distance of 36.75 kilometers against the current in 2.5 hours.

This calculation assumes a constant speed for the boat and the current, without considering factors such as changes in the current speed or the boat's speed over time.
