Question

Пешеход дошел до почты и вернулся обратно,затратив на весь путь 1ч.К почте он шел со скоростью 6 км/ч,а обратно-4 км/ч.Чему равно расстояние до почты?

Answer 1

Если бы пешеход прошел за 1 час    6км  и еще за 1час  4км то

за 2 часа он прошел бы 6+4=10км

Но поскольку пешеход шел 1час то он прошел 10:2=5км

ответ 5 км расстояние до почты

Answer 2

Calculation of the Distance to the Post Office

To find the distance to the post office, we can use the formula:

Distance = Speed x Time

Given that the pedestrian walked to the post office with a speed of 6 km/h and returned with a speed of 4 km/h, and the total time for the round trip was 1 hour, we can set up the following equation:

Distance to the post office / 6 km/h + Distance back / 4 km/h = 1 hour

Let's solve this equation to find the distance to the post office.

Step 1: Let's assume the distance to the post office is D km.

Step 2: Using the formula, we can set up the equation:

D / 6 + D / 4 = 1

Step 3: To solve this equation, we can find a common denominator and combine the fractions:

(4D + 6D) / (6 * 4) = 1

Step 4: Simplifying the equation:

10D / 24 = 1

Step 5: Cross-multiplying:

10D = 24

Step 6: Solving for D:

D = 24 / 10 = 2.4 km

Therefore, the distance to the post office is 2.4 km.
