Question

До Києва зі Львова виїхали одночасно два автомобілі. Середня швидкість руху першого з них на 10 км/год більша від швидкості другого, тому в Київ він приїхав на годину швидше. Знайдіть швидкість кожного автомобіля, якщо вважати, що відстань між цими містами 560 км.​

Answer 1

Швидкість першого 80 км/год, а другого 70км/год

Answer 2

To solve this problem, we can use the formula:

Time = Distance / Speed

Let's assume the speed of the second car is x km/h. Since the speed of the first car is 10 km/h faster, its speed would be x + 10 km/h.

The distance between Lviv and Kyiv is given as 560 km.

Now, let's calculate the time it takes for each car to travel from Lviv to Kyiv.

For the first car: Time1 = Distance / Speed1 = 560 / (x + 10)

For the second car: Time2 = Distance / Speed2 = 560 / x

According to the problem, the first car arrived in Kyiv one hour earlier than the second car. So, we can set up the equation:

Time1 = Time2 + 1

Substituting the values of Time1 and Time2, we get:

560 / (x + 10) = 560 / x + 1

To solve this equation, we can cross-multiply:

560x = 560(x + 10) + x

Simplifying further:

560x = 560x + 5600 + x

0 = 5600 + x

x = -5600

However, a negative speed is not possible in this context. Therefore, there seems to be an error in the problem statement or the given information.

Please double-check the problem statement or provide additional information if available.
