Question

Від двох причалів просташованих на відстані 315 км одночасно а зутріч один одному вийшли два теплоходи через 5 годин відстань між ними була 90 км швидкість одного теплохода 24 км/год знайдіть швидкість другого теплохода

Answer 1

1) 24х5=120 (км) - пройшов один теплоход за 5 годин
2) 315-120-90=105 (км) - пройшов другий теплоход за 5 годин
3) 105:5=21 (км/год)
Відповідь: швидкість другого теплохода 21 км/год

Answer 2

Problem Analysis

We are given that two steamboats started simultaneously from two piers located 315 km apart. After 5 hours, the distance between them was 90 km. We are also given that the speed of one steamboat is 24 km/h. We need to find the speed of the other steamboat.

Solution

Let's assume the speed of the second steamboat is x km/h.

We can use the formula: distance = speed × time to solve this problem.

After 5 hours, the first steamboat traveled a distance of 24 × 5 = 120 km.

Let's assume the distance traveled by the second steamboat in 5 hours is d km.

According to the problem, the total distance between the two steamboats after 5 hours is 90 km. Therefore, the distance traveled by the second steamboat is 315 - 90 = 225 km.

Now we can set up the equation:

120 + d = 225

Simplifying the equation, we get:

d = 225 - 120 = 105 km

Therefore, the speed of the second steamboat is 105 km / 5 hours = 21 km/h.

Answer

The speed of the second steamboat is 21 km/h.
