Question

Теплоход за 6ч прошёл 180км. На сколько нужно увеличить скорость теплохода,чтобы он прошёл то же расстояние за 4 ч?

Answer 1

180:6=30 км/час -скорость
180:4=45 км/час - нужна скорость
45-30=15 км\час
ответ на 15 км\час

Answer 2

180:6=30км за час, значит со скоростью в 45км/ч он пройдёт расстояние за 4ч

Answer 3

Problem Analysis

To solve this problem, we need to find the increase in speed required for a boat to cover the same distance in 4 hours as it did in 6 hours.

Calculation

Let's calculate the increase in speed required using the given information.

The formula to calculate speed is: Speed = Distance / Time

Given: - Distance = 180 km - Time 1 = 6 hours - Time 2 = 4 hours

Using the formula, we can calculate the initial speed of the boat and the speed required to cover the same distance in 4 hours.

Initial Speed: Speed 1 = Distance / Time 1

Speed Required: Speed 2 = Distance / Time 2

Solution

Let's calculate the initial speed and the speed required to cover the same distance in 4 hours.
