Question

Теплоход был в пути 5 дней. Два дня он проходил по 380 км в день и еще три дня - по 360 км. Сколько километров в день проходил теплоход в среднем? Сколько километров он пройдет за 6 дней , если в среднем будет проходить по столько же километров?

Answer 1

1) 380×2+360×3=760+1080=1840 (км) - средний километраж теплохода, за 5 дней
2) 1840÷5=368 (км) - средний километраж теплохода за один день
3) 368×6=2208 (км)
Ответ: теплоход в среднем проходил в день 368 км. В среднем за шесть дней он прошел 2208 км.

Answer 2

Problem Analysis

We are given that a ship was traveling for 5 days. For the first two days, it traveled at a speed of 380 km per day, and for the next three days, it traveled at a speed of 360 km per day. We need to find the average distance traveled per day and calculate how many kilometers the ship will travel in 6 days if it continues to travel the same average distance per day.

Average Distance Traveled per Day

To find the average distance traveled per day, we need to calculate the total distance traveled and divide it by the number of days. Let's calculate the total distance traveled:

Total distance traveled = (distance traveled on the first two days) + (distance traveled on the next three days)

Distance traveled on the first two days = (distance per day) * (number of days)

Distance traveled on the next three days = (distance per day) * (number of days)

Now, let's substitute the given values:

Distance traveled on the first two days = 380 km/day * 2 days = 760 km

Distance traveled on the next three days = 360 km/day * 3 days = 1080 km

Total distance traveled = 760 km + 1080 km = 1840 km

Now, let's calculate the average distance traveled per day:

Average distance traveled per day = Total distance traveled / Number of days

Average distance traveled per day = 1840 km / 5 days = 368 km/day

Therefore, the ship traveled an average of 368 km per day.

Distance Traveled in 6 Days

To calculate the distance the ship will travel in 6 days, we can multiply the average distance traveled per day by the number of days:

Distance traveled in 6 days = Average distance traveled per day * Number of days

Distance traveled in 6 days = 368 km/day * 6 days = 2208 km

Therefore, if the ship continues to travel the same average distance per day, it will travel 2208 km in 6 days.

Conclusion

In summary, the ship traveled an average of 368 km per day. If it continues to travel the same average distance per day, it will travel 2208 km in 6 days.
