Question

Автобус шёл 2 ч со скоростью 45 км/ч и 3 ч со скоростью 60 км/ч. Какой путь прошел автобус за эти 5 ч?

Answer 1

2*45+3*60=90+180=270 км

Answer 2

Решение:
Автобус проехал за 2 часа расстояние:
45*2=90 (км)
За 3 часа автобус проехал :
60*3=180 (км)
За 5 часов автобус проехал расстояние:
90 км+180км=270км

Ответ: 270км

Answer 3

Calculation of the Distance Traveled by the Bus

To calculate the distance traveled by the bus, we need to find the total distance covered during the two different time intervals.

Let's break down the problem:

- The bus traveled for 2 hours at a speed of 45 km/h. - The bus then traveled for 3 hours at a speed of 60 km/h.

To find the distance traveled during each time interval, we can use the formula:

Distance = Speed × Time

For the first time interval of 2 hours at a speed of 45 km/h:

Distance1 = 45 km/h × 2 hours

For the second time interval of 3 hours at a speed of 60 km/h:

Distance2 = 60 km/h × 3 hours

To find the total distance traveled by the bus, we add the distances covered during each time interval:

Total Distance = Distance1 + Distance2

Let's calculate the distances:

Distance1 = 45 km/h × 2 hours = 90 km Distance2 = 60 km/h × 3 hours = 180 km Total Distance = Distance1 + Distance2 = 90 km + 180 km = 270 km

Therefore, the bus traveled a total distance of 270 km during the 5-hour period.
