Question

Турист шел 6 час пешком со скоростью 5кмч и 2часа ехал на автомобиле со скоростью 45км ч найти среднюю скорость движения туриста на всем пути

Answer 1

1) 6+2=8(ч)-общее время.
2) 45+5=50(км/ч)-общая скорость.
3) 50*8=400(км/ч)-средняя скорость.
    Ответ.400км/ч

Answer 2

Calculation of Average Speed

To find the average speed of the tourist during the entire journey, we need to calculate the total distance traveled and the total time taken.

The tourist walked for 6 hours at a speed of 5 km/h, covering a distance of 6 * 5 = 30 km.

The tourist also traveled by car for 2 hours at a speed of 45 km/h, covering a distance of 2 * 45 = 90 km.

Therefore, the total distance traveled by the tourist is 30 km + 90 km = 120 km.

The total time taken for the journey is 6 hours + 2 hours = 8 hours.

To calculate the average speed, we divide the total distance by the total time:

Average speed = Total distance / Total time = 120 km / 8 hours = 15 km/h.

Therefore, the average speed of the tourist during the entire journey is 15 km/h.
