Question

Турист шел 1 ч со скоростью 4 км/ч и 4 ч со скоростью 5 км/ч. Определите среднюю скорость туриста на пройденном участке пути.

Answer 1

4км/ч+(4ч*5км/ч)=24  24/5=4,8км/ч - средняя скорость туриста

Answer 2

Сначала ищем весь путь за 5часов, он равен 4+4*5=24.
Потом 24/5=4.8км/ч

Answer 3

Calculation of Average Speed

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

The tourist walked for 1 hour at a speed of 4 km/h and then walked for 4 hours at a speed of 5 km/h.

To find the total distance traveled, we can add the distances covered during each segment of the journey.

The distance covered in the first segment is calculated by multiplying the speed (4 km/h) by the time (1 hour), which gives us 4 km.

The distance covered in the second segment is calculated by multiplying the speed (5 km/h) by the time (4 hours), which gives us 20 km.

Therefore, the total distance traveled is 4 km + 20 km = 24 km.

To find the total time taken, we can add the times taken for each segment of the journey.

The time taken in the first segment is 1 hour.

The time taken in the second segment is 4 hours.

Therefore, the total time taken is 1 hour + 4 hours = 5 hours.

Now, we can calculate the average speed by dividing the total distance traveled by the total time taken.

Average speed = Total distance / Total time

Average speed = 24 km / 5 hours

Average speed = 4.8 km/h

Therefore, the average speed of the tourist on the given stretch of the journey is 4.8 km/h.
