Question

Машина идёт со скоростью 65 км/ч. До цели путешествия осталось проехать 180 км. Успеет ли машина проехать это путь за 2 часа?,а за 3 часа?

Answer 1

1) за 2 часа
65 • 2 = 130 ( км )
180 км > 130 км
Ответ не успеет
2) за 3 часа
65 • 3 = 195 ( км )
180 км < 195 км
Ответ успеет

Answer 2

Calculation of Time Required to Travel 180 km at a Speed of 65 km/h

To determine if a car traveling at a speed of 65 km/h can cover a distance of 180 km in 2 hours or 3 hours, we can calculate the time required to travel the given distance at the given speed.

The formula to calculate time is:

Time = Distance / Speed

Let's calculate the time required for the car to travel 180 km at a speed of 65 km/h:

Time = 180 km / 65 km/h

Using this formula, we can calculate the time required for the car to travel the given distance.

Calculation for 2 Hours:

To determine if the car can cover the distance of 180 km in 2 hours, we substitute the values into the formula:

Time = 180 km / 65 km/h = 2.769 hours

Since the calculated time is approximately 2.769 hours, which is greater than 2 hours, the car will not be able to cover the distance of 180 km in 2 hours.

Calculation for 3 Hours:

To determine if the car can cover the distance of 180 km in 3 hours, we substitute the values into the formula:

Time = 180 km / 65 km/h = 2.769 hours

Since the calculated time is approximately 2.769 hours, which is less than 3 hours, the car will be able to cover the distance of 180 km in 3 hours.

Therefore, the car will not be able to cover the distance of 180 km in 2 hours, but it will be able to cover the same distance in 3 hours.

Please note that the above calculations are based on the assumption that the car will maintain a constant speed of 65 km/h throughout the journey.
