Question

До остановки автобус проехал 150 км за 2 часа, затем он увеличил скорость на 15 км/ч и проехал 3 часа. Какое общее расстояние проехал автобус? (можно по действиям)

Answer 1

1) 3*2=6 ч
2)150+15=165 ответ

Answer 2

1) ищем скорость до остановки- 150/2=75 км/ч.
2) скорость изменилась на 15 км/ч.- 75+15= 90 км/ч.
3) ищем расстояние после остановки- 90*3= 270 км.
4) ищем общее расстояние- 150+270=420 км
Ответ: 420 км.

Answer 3

Calculation of the Total Distance Traveled by the Bus

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

1. Distance covered in the first 2 hours: - The bus traveled 150 km in 2 hours. - Therefore, the average speed during this time interval was 150 km / 2 hours = 75 km/h.

2. Distance covered in the next 3 hours: - The bus increased its speed by 15 km/h. - So, the new speed during this time interval was 75 km/h + 15 km/h = 90 km/h. - The time interval was 3 hours. - Therefore, the distance covered during this time interval was 90 km/h * 3 hours = 270 km.

3. Total distance traveled by the bus: - To find the total distance, we add the distances covered during the two time intervals: 150 km + 270 km = 420 km.

Therefore, the bus traveled a total distance of 420 km.
