Question

Автобус ехал 3ч со скоростью 54 км/ч.оказалось,что он проехал 9/14 всего пути.сколько всего километров он должен проехать?с какой скоростью надо ехать автобусу.чтобы преодолеть оставшееся расстояние за 2 ч?

Answer 1

54*3=162 км-проехал автобус

162:9814=252 км- он должен был проехать всего

252-162=90км- осталось проехать

90:2=45 км/ч- нужная скорость

Answer 2

54 * 3=162км = 9/14

162 : 9/14 = 252 км должен проехать

252 - 162=90 км осталось

90 : 2 = 45 км/час должен ехать

Answer 3

Calculation of Total Distance and Required Speed

To calculate the total distance the bus needs to travel and the speed required to cover the remaining distance in 2 hours, we can use the information provided.

Given: - The bus traveled for 3 hours at a speed of 54 km/h. - It covered 9/14 of the total distance.

Let's calculate the total distance first.

To find the total distance, we can use the formula:

Total Distance = Distance Covered / (Fraction of Distance Covered)

In this case, the distance covered is 9/14 of the total distance.

Let's substitute the values into the formula:

Total Distance = (9/14) * Distance Covered

Now, let's calculate the total distance:

Total Distance = (9/14) * Distance Covered

To find the distance covered, we can use the formula:

Distance Covered = Speed * Time

In this case, the speed is 54 km/h and the time is 3 hours.

Let's substitute the values into the formula:

Distance Covered = 54 km/h * 3 hours

Now, let's calculate the distance covered:

Distance Covered = 54 km/h * 3 hours

To find the total distance, we can substitute the value of the distance covered into the formula:
