Question

Машина прошла первый участок пути за 5 часов а второй участок за 3 часа длина обоих участков вместе 526 км с какой скоростью шла машина на каждом участке если скорость на втором участке было на 10 км в час больше чем на Первом

Answer 1

Х - скорость а первом участке
х+10 - скорость на втором
5х+3(х+10)=526
5х+3х+30=526
8х=526-30
8х=496
х=496:8
х=62 (км/ч) на первом
62+10=72 (км/ч) на втором
Ответ: на первом участке машина шла со скоростью 62 км/ч, на втором 72 км/ч

проверка
62*5+72*3=526
310+216=526
526=526

Answer 2

Problem Analysis

We are given that a car traveled the first segment of the journey in 5 hours and the second segment in 3 hours. The total length of both segments is 526 km. We need to find the speed of the car on each segment, given that the speed on the second segment was 10 km/h faster than on the first segment.

Solution

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

To find the speed of the car on each segment, we can use the formula:

Speed = Distance / Time

Let's calculate the speed on each segment.

Calculation

The total distance traveled is 526 km. The time taken for the first segment is 5 hours, and for the second segment is 3 hours.

For the first segment: Speed of the car on the first segment = Distance / Time = 526 km / 5 hours = 105.2 km/h.

For the second segment: Speed of the car on the second segment = Distance / Time = 526 km / 3 hours = 175.3 km/h.

Therefore, the car traveled at a speed of 105.2 km/h on the first segment and 175.3 km/h on the second segment.

Answer

The car traveled at a speed of 105.2 km/h on the first segment and 175.3 km/h on the second segment.

Note: The answer is rounded to one decimal place for simplicity.
