Answer 2

Calculation of Distance Traveled

To calculate the total distance traveled by the train, we need to add up the distances covered at each speed.

The train traveled 18 km at a speed of 76 km/h and then an additional distance at a speed of 72 km/h.

Let's calculate the distance traveled at each speed and then add them together to find the total distance.

1. Distance traveled at 76 km/h: - Speed: 76 km/h - Time: Unknown - Distance: 18 km

2. Distance traveled at 72 km/h: - Speed: 72 km/h - Time: Unknown - Distance: Unknown

To find the time taken at each speed, we can use the formula:

Time = Distance / Speed

Let's calculate the time taken at each speed and then find the total distance traveled.

1. Time taken at 76 km/h: - Distance: 18 km - Speed: 76 km/h - Time = 18 km / 76 km/h = 0.2368 hours

2. Time taken at 72 km/h: - Distance: Unknown - Speed: 72 km/h - Time = Unknown / 72 km/h = Unknown

Now, let's find the distance traveled at 72 km/h using the time calculated at 76 km/h.

Distance = Speed * Time

1. Distance traveled at 72 km/h: - Speed: 72 km/h - Time: 0.2368 hours - Distance = 72 km/h * 0.2368 hours = 17.0496 km

Finally, let's find the total distance traveled by adding the distances traveled at each speed:

Total Distance = Distance at 76 km/h + Distance at 72 km/h

Total Distance = 18 km + 17.0496 km = 35.0496 km

Therefore, the train traveled a total distance of approximately 35.0496 km during this time.
