Answer 1

Ответ:

1) 2*15=30км

2) 30+70=100км

Answer 2

Calculating the Total Distance Traveled by the Bus

To calculate the total distance traveled by the bus, we can use the formula for distance, which is speed multiplied by time.

1. First Hour: The bus traveled at a speed of 70 km/h for the first hour. 2. Next 2 Hours: For the next 2 hours, the bus traveled at a speed 15 km/h greater than the initial speed of 70 km/h.

Let's calculate the distance traveled for each segment of the journey.

Calculating Distance for Each Segment

1. First Hour: - Distance = Speed * Time - Distance = 70 km/h * 1 h - Distance = 70 km

2. Next 2 Hours: - Speed = 70 km/h + 15 km/h (increase in speed) - Distance = Speed * Time - Distance = (70 km/h + 15 km/h) * 2 h - Distance = 85 km/h * 2 h - Distance = 170 km

Calculating the Total Distance

To find the total distance traveled by the bus, we add the distances for each segment of the journey.

Total Distance = Distance for First Hour + Distance for Next 2 Hours Total Distance = 70 km + 170 km Total Distance = 240 km

Therefore, the total distance traveled by the bus is 240 km.
