Question

Турист 4 год йшов пішки з швидкістю 5 км/год, а потім 6 год їхав поїздом з швидкістю 90 км/ год. Яка середня швидкість туриста на всьому шляху?​

Answer 1

Ответ:

Пошаговое объяснение:

4 * 5 = 20 км пройшов пішки

6 * 90 = 540 км проїхав поїздом

4 + 6 = 10 годин час, витрачений на весь шлях

540 + 20 = 560 км весь шлях

560 : 10 = 56 км/год середня швидкість туриста на всьому шляху

Answer 2

Calculating the Average Speed

To calculate the average speed of the tourist over the entire journey, we first need to calculate the distance traveled during each part of the trip.

The tourist walked for 4 hours at a speed of 5 km/h. To calculate the distance walked, we use the formula:

`Distance = Speed x Time`

Plugging in the values:

`Distance Walked = 5 km/h x 4 hours = 20 km`

The tourist then traveled by train for 6 hours at a speed of 90 km/h. Using the same formula:

`Distance by Train = 90 km/h x 6 hours = 540 km`

To calculate the total distance traveled:

`Total Distance = Distance Walked + Distance by Train` = 20 km + 540 km = 560 km

Now we can calculate the total time taken:

`Time Walking = 4 hours` `Time by Train = 6 hours` `Total Time = Time Walking + Time by Train` = 4 hours + 6 hours = 10 hours

Finally, to calculate the average speed:

`Average Speed = Total Distance / Total Time`

Plugging in the values:

`Average Speed = 560 km / 10 hours` = 56 km/h

Therefore, the average speed of the tourist over the entire journey was 56 km/h.
