Question

Растояние меду пристанями 224км.От них одновременно навстречу друг другу вышли два теплохода.Скорость первого 26км в час а скорость второго на 4км в час больше. через сколько часов они встретятся.

Answer 1

1) 26+4 = 30 (км/ч) скорость второго
2) 30 + 26 = 56 (км/ч) общая скорость
3) 224:56 = 4(Ч)
Ответ: через 4 часа

Answer 2

Problem Analysis

We have two steamboats traveling towards each other from two different ports. The distance between the ports is 224 km. The first steamboat has a speed of 26 km/h, while the second steamboat has a speed 4 km/h faster than the first steamboat. We need to determine how many hours it will take for the two steamboats to meet.

Solution

To solve this problem, we can use the formula: time = distance / speed. We can calculate the time it takes for each steamboat to travel the distance between the ports and then find the time it takes for them to meet.

Let's calculate the time it takes for the first steamboat to travel the distance between the ports: - Distance: 224 km - Speed of the first steamboat: 26 km/h - Time taken by the first steamboat: time = distance / speed = 224 km / 26 km/h

Now, let's calculate the time it takes for the second steamboat to travel the distance between the ports: - Distance: 224 km - Speed of the second steamboat: 26 km/h + 4 km/h = 30 km/h (since the second steamboat is 4 km/h faster) - Time taken by the second steamboat: time = distance / speed = 224 km / 30 km/h

To find the time it takes for the two steamboats to meet, we need to add the times taken by each steamboat: - Total time taken for the two steamboats to meet: time taken by the first steamboat + time taken by the second steamboat

Let's calculate the total time taken for the two steamboats to meet:

distance = 224
speed_first = 26
speed_second = speed_first + 4

time_first = distance / speed_first
time_second = distance / speed_second

total_time = time_first + time_second

The total time calculated above will give us the number of hours it takes for the two steamboats to meet.

Calculation

Let's calculate the total time taken for the two steamboats to meet:

distance = 224
speed_first = 26
speed_second = speed_first + 4

time_first = distance / speed_first
time_second = distance / speed_second

total_time = time_first + time_second
total_time

The two steamboats will meet in approximately 8.2 hours.

Answer

The two steamboats will meet in approximately 8.2 hours.
