Question

Путешественник 1 час 30 мин ехал со скоростью 10 км/ч на верблюде и потом 3 часа-на осле со скоростью 16 км/ч. Какой была средняя скорость путешественника на всем пути? ОБЪЯСНИТЕ ПОЖАЛУЙСТА ПОДРОБНО:С

Answer 1

1) Общий путь:
1.5 * 10 = 15 км
3 * 16 = 48 км
15 + 48 = 63 км - общий путь
2) Общее время:
1.5 + 3 = 4.5 часов
3) Средняя скорость
63 : 4.5 = 14 (км\час)
Ответ: 14 км\час

Answer 2

Calculation of Average Speed

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

Let's break down the given information:

- The traveler traveled for 1 hour and 30 minutes (or 1.5 hours) at a speed of 10 km/h on a camel. - The traveler then traveled for 3 hours at a speed of 16 km/h on a donkey.

To find the total distance traveled, we can add the distances traveled on the camel and the donkey:

- Distance traveled on the camel = speed * time = 10 km/h * 1.5 hours = 15 km - Distance traveled on the donkey = speed * time = 16 km/h * 3 hours = 48 km

The total distance traveled is the sum of these distances: 15 km + 48 km = 63 km.

To find the total time taken, we can add the times spent on the camel and the donkey:

- Time spent on the camel = 1.5 hours - Time spent on the donkey = 3 hours

The total time taken is the sum of these times: 1.5 hours + 3 hours = 4.5 hours.

Now, we can calculate the average speed using the formula:

Average Speed = Total Distance / Total Time

Substituting the values we found earlier:

Average Speed = 63 km / 4.5 hours = 14 km/h

Therefore, the average speed of the traveler on the entire journey was 14 km/h.
