Question

Парты в классе стоят на одинаковом расстоянии друг от друга. От первой парты до доски 3,5 метра, а от пятой – 9,5 метров. На каком расстоянии от доски находится третья парта? Ответ дайте в метрах.

Answer 1

9,5-3,5=6м расстояние от первой парты до пятой

6:4=1,5м расстояние между партами

3,5+1,5=5 м вторая парта

5+1,5=6,5м третья парта

ответ: третья парта находится от доски на 6,5м

Answer 2

9,5-3,5=6 метров - между первой и пятой партами

6/4=1,5м - между каждой партой

3,5+1,5+1,5=6,5м

Ответ. между доской и третьей партой 6,5м

Answer 3

Calculation of the Distance

To determine the distance at which the third desk is located from the board, we can use the information provided. We know that the distance from the first desk to the board is 3.5 meters, and the distance from the fifth desk to the board is 9.5 meters. We need to find the distance from the board to the third desk.

To calculate this, we can subtract the distance from the board to the fifth desk from the distance from the board to the first desk, and then divide the result by 4 (since there are four desks between the first and fifth desks). This will give us the distance between each desk.

Let's perform the calculation:

Distance between each desk = (Distance from the board to the first desk - Distance from the board to the fifth desk) / 4

Distance between each desk = (3.5 meters - 9.5 meters) / 4

Distance between each desk = -6 meters / 4

Distance between each desk = -1.5 meters

Since the calculated distance is negative, it suggests that the desks are arranged in the opposite direction. Therefore, we need to take the absolute value of the calculated distance to get the positive value.

Distance between each desk = |-1.5 meters| = 1.5 meters

Now, we can determine the distance from the board to the third desk by multiplying the distance between each desk by 2 (since the third desk is two desks away from the first desk).

Distance from the board to the third desk = Distance between each desk * 2

Distance from the board to the third desk = 1.5 meters * 2

Distance from the board to the third desk = 3 meters

Therefore, the third desk is located 3 meters away from the board.
