Question

11 Два автомобиля ехали с одинаковой скоростью. Один из них проехал 360 км, а другой-480 км.Сколько часов был в пути каждый автомобиль,если первый был в пути на 2 часа меньше, чем второй? Помогите пожалуйста

Answer 1

Ответ:

8ч ,6ч

Пошаговое объяснение:

1)480-360=120 км больше чем первый

2)120÷2=60 км /ч

3)480÷60=8ч второй

4)360÷60=6ч первый

Answer 2

Calculating Travel Time for Two Cars

To calculate the travel time for each car, we can use the formula: time = distance / speed. Given that both cars traveled at the same speed, we can calculate the time each car spent on the road.

Let's denote: - Distance traveled by the first car as D1 = 360 km - Distance traveled by the second car as D2 = 480 km - Speed of both cars as S

We also know that the first car was on the road for 2 hours less than the second car.

Using the formula, the time each car spent on the road can be calculated as follows:

For the first car: time1 = D1 / S

For the second car: time2 = D2 / S

Given that the first car was on the road for 2 hours less than the second car: time1 = time2 - 2

Let's solve for the time each car spent on the road.

Calculating Travel Time for the First Car

Using the formula time1 = D1 / S, we can calculate the time the first car spent on the road.

time1 = 360 / S

Calculating Travel Time for the Second Car

Using the formula time2 = D2 / S, we can calculate the time the second car spent on the road.

time2 = 480 / S

Finding the Relationship Between the Travel Times

Given that the first car was on the road for 2 hours less than the second car: time1 = time2 - 2

Solving for the Speed

To solve for the speed of the cars, we can set up the equation: 360 / S = 480 / S - 2

By solving this equation, we can find the value of S.

Let's solve for the speed of the cars.
