Question

Дорога от школы и обратно занимает у Ольги 1/2 часа. в школу она идёт со скоростью 6 км/ч, а обратно-3км/ч. чему равно расстояние от дома до школы?

Answer 1

Пусть расстояние от дома до школы равно x

Пользуясь формулой времени t=S/V, составим и решим уравнение

0,5=x/6+x/3

3=x+2x

3x=3

x=1

Ответ: 1км

Answer 2

Calculation of the Distance from Home to School

To calculate the distance from home to school, we can use the formula:

Distance = Speed × Time

Given that Olga takes half an hour (1/2 hour) to travel from school to home and vice versa, we can calculate the distance using the speeds at which she walks.

- Speed from home to school: 6 km/h - Speed from school to home: 3 km/h - Time taken for one trip: 1/2 hour

Let's calculate the distance from home to school:

Distance from home to school = Speed from home to school × Time taken for one trip

Substituting the values:

Distance from home to school = 6 km/h × 1/2 hour

Simplifying the equation:

Distance from home to school = 3 km

Therefore, the distance from home to school is 3 kilometers.
