Question

Расстояние от спинки кота, спящего на полу, до кончика уха кота, сидящего на столе, равно 150 см. Расстояние от кончика уха кота, сидящего на полу, до спинки кота, спящего на столе, равно 110 см. Какова высота стола?

Answer 1

Пусть спящего кота m, сидящего кота - b, стола - s.
В первом случае:
$s+b=m+150$
Во втором случае:
$s+m=b+110$
Суммируем два уравнения:
$s+b+s+m=m+150+b+110 \\\ 2s=260 \\\ s=130$
Ответ: 130 см

Answer 2

Calculation of the Table Height

To calculate the height of the table, we can use the given information about the distances between the cat's ear and the cat's back when sitting on the floor and on the table.

The distance from the cat's back when it is sleeping on the floor to the tip of its ear when it is sitting on the table is 150 cm.

The distance from the tip of the cat's ear when it is sitting on the floor to the cat's back when it is sleeping on the table is 110 cm.

To find the height of the table, we need to subtract the distance from the cat's back to the tip of its ear when sitting on the floor from the distance from the cat's back to the tip of its ear when sitting on the table.

Therefore, the height of the table can be calculated as follows:

Height of the table = Distance from the cat's back to the tip of its ear when sitting on the table - Distance from the cat's back to the tip of its ear when sitting on the floor

Height of the table = 150 cm - 110 cm = 40 cm

So, the height of the table is 40 cm.
