Question

Из двух городов, расстояние между которыми 1204 км, одновременно выехали два автомобиля, скорость первого 58 км в час, скорлсть второго в 2 раза больше. Через сколько они встретяться,,?

Answer 1

58*2=116 км/ч скорость 2-ого
58+116=174 км/ч общая скорость
1204:174=6 ч

Answer 2

1)58*2=116(км/час)скорость 2
2)116+58=174(км/ч)вместе
3)1204:174=6(ч)встретятся

Answer 3

Problem Analysis

We have two cars that start at the same time from two different cities, and we need to find out when they will meet. The distance between the cities is 1204 km, and the first car has a speed of 58 km/h, while the second car has a speed twice that of the first car.

Solution

To find out when the two cars will meet, we can use the formula: time = distance / relative speed.

Let's calculate the relative speed of the two cars first. Since the second car's speed is twice that of the first car, the relative speed will be the sum of their speeds: 58 km/h + 2 * 58 km/h = 58 km/h + 116 km/h = 174 km/h.

Now we can calculate the time it will take for the two cars to meet by dividing the distance between the cities by the relative speed: time = 1204 km / 174 km/h.

Calculation

Let's calculate the time it will take for the two cars to meet:

time = 1204 km / 174 km/h

Using a calculator, we find that the time is approximately 6.92 hours.

Answer

Therefore, the two cars will meet approximately 6.92 hours after they start their journey.

Please note that this is an approximate calculation and does not take into account factors such as traffic, breaks, or changes in speed during the journey.
