Question

Электровоз прошёл 720 км причём 6,ч. он шёл со скоростью 80 км час оставшийся путь со скоростью 60 километров в час какое время электровоз был в пути

Answer 1

Calculation of the Time Taken by the Electric Locomotive

To calculate the time taken by the electric locomotive, we need to consider the distance traveled at different speeds.

Given information: - Distance traveled at a speed of 80 km/h: 720 km - Remaining distance traveled at a speed of 60 km/h

Let's calculate the time taken for each part of the journey:

1. Distance traveled at 80 km/h: - Distance: 720 km - Speed: 80 km/h - Time taken = Distance / Speed = 720 km / 80 km/h = 9 hours

2. Remaining distance traveled at 60 km/h: - Distance: Remaining distance - Speed: 60 km/h - Time taken = Distance / Speed

To calculate the remaining distance, we subtract the distance traveled at 80 km/h from the total distance:

Remaining distance = Total distance - Distance traveled at 80 km/h Remaining distance = 720 km - 720 km = 0 km

Since the remaining distance is 0 km, the time taken to travel this distance is 0 hours.

Therefore, the total time taken by the electric locomotive is the sum of the time taken for each part of the journey:

Total time taken = Time taken at 80 km/h + Time taken at 60 km/h Total time taken = 9 hours + 0 hours = 9 hours

The electric locomotive was in transit for 9 hours.
