Question

Автобус шёл 2 ч со скоростью 45км/ч и 3ч со скоростью 60км/ч какой путь прошёл автобус за эти 5ч?

Answer 1

1) 45 км/ч * 2= 90 км- проехал автобус за  2 часа.
2) 60 км/ч * 3= 180 км- проехал автобус за 3 часа.
3) 90+180 = 270 км
Ответ: 270 км проехал автобус за эти 5 часов

Answer 2

Calculation of the Distance Traveled by the Bus

To calculate the distance traveled by the bus, we need to find the sum of the distances covered during the two time intervals.

Let's break down the problem step by step:

1. The bus traveled for 2 hours at a speed of 45 km/h. 2. The distance covered during this time can be calculated using the formula: distance = speed × time. - For the first 2 hours, the distance covered is: distance1 = 45 km/h × 2 h.

3. The bus then traveled for 3 hours at a speed of 60 km/h. 4. The distance covered during this time can be calculated using the same formula: distance = speed × time. - For the next 3 hours, the distance covered is: distance2 = 60 km/h × 3 h.

5. To find the total distance traveled by the bus, we need to add the distances covered during the two time intervals: total distance = distance1 + distance2.

Let's calculate the distances:

1. The distance covered during the first 2 hours is: - distance1 = 45 km/h × 2 h = 90 km.

2. The distance covered during the next 3 hours is: - distance2 = 60 km/h × 3 h = 180 km.

3. Therefore, the total distance traveled by the bus in 5 hours is: - total distance = distance1 + distance2 = 90 km + 180 km = 270 km.

So, the bus traveled a distance of 270 kilometers during the 5-hour period.
