The graph shows the distance (S, km) versus time (t, ч). Line 1 represents the movement of one object, and line 2 represents another.
We need to determine the speed of the object represented by line 1. Speed is calculated as the change in distance divided by the change in time ($$ ext{speed} = rac{\Delta S}{\Delta t}$$).
From the graph, we can approximate two points on line 1:
Now, we calculate the change in distance ($$\Delta S$$) and the change in time ($$\Delta t$$):
Now, we can calculate the speed:
$$\text{Speed} = \frac{\Delta S}{\Delta t} = \frac{60 \text{ км}}{9 \text{ ч}}$$
Calculating the value:
$$\frac{60}{9} \approx 6.67$$
Therefore, the approximate speed of the object represented by line 1 is 6.67 km/h.
Ответ: 6.67 км/ч
