Question

От пристани Волгограда отошли одновременно в противоположных направлениях два теплохода. Через 4 часа расстояние между ними стало 268 километров. Скорость первого теплохода 35 километров в час. Найди скорость второго теплохода.

Answer 1

35X4=140 км прошел первый
268-140=128км прошел второй
128:4=32 км,ч скорость второго

Answer 2

Answer in detail. Two steamboats left the Volgograd pier at the same time in opposite directions. After 4 hours, the distance between them became 268 kilometers. The speed of the first steamboat is 35 kilometers per hour. Find the speed of the second steamboat.

To solve this problem, we can use the formula for the distance between two moving objects:

$$d = (v_1 + v_2) \times t$$

where $d$ is the distance, $v_1$ and $v_2$ are the speeds of the objects, and $t$ is the time.

We can plug in the given values into the formula and solve for $v_2$:

$$268 = (35 + v_2) \times 4$$

$$67 = 35 + v_2$$

$$v_2 = 67 - 35$$

$$v_2 = 32$$

Therefore, the speed of the second steamboat is 32 kilometers per hour.
