Question

Первый час автобус ехал со скоростью 60км/ч а в течение двух следующих часов его скорость была на 10км/ч меньше.

Answer 1

Ну может:
Если потом скорость стала на 10 км/ч меньше чем была:
60 км/ч - 10 км/ч = 50 км/ч
Для того чтобы узнать расстояние которое автобус проехал за 3 часа,нужно:
50 * 3 = 150 км - проехал автобус за эти 3 часа

Answer 2

1)60-10=50
2)50*2=100
3)100+60=160

Answer 3

Calculating the Average Speed of the Bus

To calculate the average speed of the bus, we can use the formula:

Average Speed = Total Distance / Total Time

Let's break down the problem step by step.

1. First Hour: The bus traveled at a speed of 60 km/h for the first hour. 2. Next Two Hours: For the next two hours, the bus's speed was 10 km/h less than the initial speed.

Calculating the Total Distance Traveled

To calculate the total distance traveled, we can use the formula:

Distance = Speed × Time

1. First Hour: Distance = 60 km/h × 1 h = 60 km 2. Next Two Hours: Distance = (60 km/h - 10 km/h) × 2 h = 100 km

So, the total distance traveled by the bus is 60 km + 100 km = 160 km.

Calculating the Total Time

The total time can be calculated by adding the individual times.

1. First Hour: 1 hour 2. Next Two Hours: 2 hours

Total Time = 1 hour + 2 hours = 3 hours

Calculating the Average Speed

Now, we can use the formula for average speed:

Average Speed = Total Distance / Total Time

Average Speed = 160 km / 3 hours = 53.33 km/h

Therefore, the average speed of the bus over the 3-hour period is 53.33 km/h.
