Answer 1

Ответ:

S = 375 км

Пошаговое объяснение:

S1 = 4 * 45 = 180

S2 = 3 * 65 = 195

S = 180 + 195 = 375

---------->-------------------->

  S1                   S2

Answer 2

Ответ:

1) 45*4=180

2) 65*3=195

3) 180+195=375(км)

Ответ: 375 км прошел поезд до места назначения.

Answer 3

Calculating the Distance Traveled by the Train

To calculate the distance traveled by the train, we can use the formula:

Distance = Speed × Time

The train traveled at two different speeds for different durations. We can calculate the distance traveled for each segment and then sum them up to find the total distance traveled.

1. Calculating the distance for the first 4 hours at 45 km/h: - Speed = 45 km/h - Time = 4 hours - Using the formula, Distance = Speed × Time - Distance = 45 km/h × 4 h = 180 km

2. Calculating the distance for the next 3 hours at 65 km/h: - Speed = 65 km/h - Time = 3 hours - Using the formula, Distance = Speed × Time - Distance = 65 km/h × 3 h = 195 km

Total Distance Traveled

- Adding the distances for the two segments: - Total Distance = 180 km + 195 km = 375 km

Therefore, the train traveled a total distance of 375 kilometers to its destination.

I hope this helps! If you have any other questions, feel free to ask.
