Answer 1

102,9:2=51.5км/ч
51.5+6.5=58км/ч
58*2=116км

(102,9:2)+6.5*2=116км

Answer 2

Problem Analysis

The problem states that a car traveled 102.9 km in 2 hours and that in the first hour it traveled 6.5 km more than in the second hour. We need to determine how many kilometers the car traveled in the second hour.

Solution

Let's assume that the car traveled x kilometers in the second hour. According to the problem, in the first hour it traveled x + 6.5 kilometers.

To find the total distance traveled in 2 hours, we can add the distances traveled in each hour:

x + (x + 6.5) = 102.9

Simplifying the equation:

2x + 6.5 = 102.9

Subtracting 6.5 from both sides:

2x = 96.4

Dividing both sides by 2:

x = 48.2

Therefore, the car traveled 48.2 km in the second hour.

Answer

The car traveled 48.2 km in the second hour.

Explanation

Let's verify the solution by substituting the value of x back into the equation:

48.2 + (48.2 + 6.5) = 102.9

48.2 + 54.7 = 102.9

102.9 = 102.9

The equation is balanced, which confirms that the solution is correct.
