Answer 1

(13+13+4)*0,5=15 км
ответ: 15км

Answer 2

1) 13+4=17 2) 17*0.5+13*0.5 =15 км Ответ: через 30 мин расстояние будет 15 км

Answer 3

Problem Analysis

Two cyclists start from point A in opposite directions. The first cyclist travels at a speed of 13 km/h, while the second cyclist travels at a speed 4 km/h faster than the first. We need to determine the distance between the two cyclists after half an hour.

Solution

To find the distance between the two cyclists after half an hour, we can use the formula: distance = speed * time

The first cyclist travels at a speed of 13 km/h, so in half an hour, the first cyclist will have traveled: distance_first_cyclist = 13 km/h * 0.5 h

The second cyclist travels at a speed 4 km/h faster than the first, so the speed of the second cyclist is: speed_second_cyclist = 13 km/h + 4 km/h

Therefore, the distance traveled by the second cyclist in half an hour is: distance_second_cyclist = (13 km/h + 4 km/h) * 0.5 h

Calculation

Let's calculate the distances traveled by each cyclist:

- The distance traveled by the first cyclist is: distance_first_cyclist = 13 km/h * 0.5 h = 6.5 km

- The distance traveled by the second cyclist is: distance_second_cyclist = (13 km/h + 4 km/h) * 0.5 h = 8.5 km

Conclusion

After half an hour, the two cyclists will be 6.5 km apart from each other.
