Question

СРОЧНО!!!! надо решиь задачку 6 класа. мотоцикліст проїхав певну відстань за 3 цілих п'ять десятих години автомобіліст Швидкість якого на 10 км на годину більше проїхав цю відстань за 3 години З якою швидкістю рухався Автомобіліст

Answer 1

Ответ:

Х- швидкість мотоцикліста

Х+10-швидкість автомобіліста

3,5х-шлях мотоцикліста

3(х+10) - шлях автомобіліста

За умовою відстань була однакова.

Складемо рівняння і розв'яжемо його.

3,5х=3(х+10)

3,5х=3х+30

3,5х-3х=30

0,5х=30(÷0,5)

х=60км/год - швидкість мотоцикліста

60+10=70(км/год) - швидкість автомобіліста.

Answer 2

Based on the search results, the problem states that a motorcyclist traveled a certain distance in 3.5 hours, while a driver, whose speed was 10 km/h faster, covered the same distance in 3 hours. We need to find the speed of the driver.

To solve this problem, we can use the formula: Speed = Distance / Time.

Let's calculate the speed of the motorcyclist first. We know that the motorcyclist traveled a certain distance in 3.5 hours. Let's assume the distance is represented by D.

The speed of the motorcyclist can be calculated as: Speed of Motorcyclist = D / 3.5.

Next, let's calculate the speed of the driver. We know that the driver covered the same distance in 3 hours and their speed was 10 km/h faster than the motorcyclist.

The speed of the driver can be calculated as: Speed of Driver = (D / 3) + 10.

To find the speed of the driver, we need to equate the two expressions for speed and solve for D.

Let's set up the equation:

(D / 3.5) = (D / 3) + 10

Now, let's solve the equation step by step:

Multiply both sides of the equation by 3.5 and 3 to eliminate the denominators:

3(D) = 3.5(D) + 30

Expand the equation:

3D = 3.5D + 30

Subtract 3.5D from both sides of the equation:

3D - 3.5D = 30

Combine like terms:

-0.5D = 30

Divide both sides of the equation by -0.5:

D = -60

Since distance cannot be negative, there seems to be an error in the problem statement or the calculations. Please double-check the problem or provide additional information if available.
