Question

Автомобиль проехал 180 км за 3 часа с одинаковой скоростью из-за гололеда на обратном пути он уменьшил скорость на 15 км в час сколько времени затратил автомобиль на обратный путь

Answer 1

1)180:3=60(км)- за 1 час
2) 60 - 15=45(км\ч)-на обратном пути
3)180:45=4(ч.)

Answer 2

180 разделить на 3 = 60 километров в час - скорость автомобиля.
60 - 15 = 45 километров в час - скорость автомобиля, при гололеде.
180 разделить на 45 = 4 часа затратил автомобиль на обратный путь.

Answer 3

Calculation of Time for the Return Journey

To calculate the time taken for the return journey, we need to consider the reduced speed due to icy road conditions.

Given: - Distance traveled: 180 km - Time taken for the forward journey: 3 hours - Speed reduction on the return journey: 15 km/h

To find the time taken for the return journey, we can use the formula:

Time = Distance / Speed

Let's calculate the time taken for the return journey step by step:

1. Calculate the speed on the return journey: - Speed on the forward journey: Not mentioned explicitly, so we'll assume it to be constant. - Speed reduction on the return journey: 15 km/h - Speed on the return journey = Speed on the forward journey - Speed reduction - Speed on the return journey = (Speed on the forward journey) - 15 km/h

2. Calculate the time taken for the return journey: - Time = Distance / Speed - Time = 180 km / (Speed on the return journey)

Let's calculate the time taken for the return journey using the given information.

Calculation Steps:

1. Calculate the speed on the return journey: - Speed on the forward journey: Not mentioned explicitly, so we'll assume it to be constant. - Speed reduction on the return journey: 15 km/h - Speed on the return journey = Speed on the forward journey - Speed reduction - Speed on the return journey = (Speed on the forward journey) - 15 km/h

2. Calculate the time taken for the return journey: - Time = Distance / Speed - Time = 180 km / (Speed on the return journey)

Calculation:

1. Calculate the speed on the return journey: - Speed on the forward journey: Not mentioned explicitly, so we'll assume it to be constant. - Speed reduction on the return journey: 15 km/h - Speed on the return journey = Speed on the forward journey - Speed reduction - Speed on the return journey = (Speed on the forward journey) - 15 km/h

2. Calculate the time taken for the return journey: - Time = Distance / Speed - Time = 180 km / (Speed on the return journey)

Since the speed on the forward journey is not mentioned explicitly, we cannot calculate the exact time taken for the return journey without this information.
