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? Решить в системе СИ

Answer 1

S=1.5*10+3*16=15+48=63км
T=1.5+3=4.5
V=63/4.5=14км/ч=3,89 м/c

Answer 2

Calculation of Average Speed

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

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

Let's calculate the total distance traveled:

Distance traveled on the camel = Speed x Time = 10 km/h x 1.5 hours = 15 km

Distance traveled on the donkey = Speed x Time = 16 km/h x 3 hours = 48 km

Total distance traveled = Distance on camel + Distance on donkey = 15 km + 48 km = 63 km

Now, let's calculate the total time taken:

Total time taken = Time on camel + Time on donkey = 1.5 hours + 3 hours = 4.5 hours

Finally, we can calculate the average speed:

Average speed = Total distance traveled / Total time taken = 63 km / 4.5 hours = 14 km/h

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