Andrea made a car trip of 440 Kilometers. She averaged 54 Kilometers per hour for the frst part of the trip and 80 kilometers per hour for the secound part. If the total trip took 6 hours, how long was she traveling at 80 kilometers per hour?

To find out how long Andrea was traveling at 80 kilometers per hour, we can first calculate the time it took for the first part of the trip by using the formula:

Time (first part) = Distance (first part) / Speed (first part)

We are given that the first part of the trip covered a distance of 440 kilometers at an average speed of 54 kilometers per hour. Plugging in these values, we get:

Time (first part) = 440 kilometers / 54 kilometers per hour ≈ 8.148 hours

Now, let's calculate the time it took for the second part of the trip:

Time (second part) = Total Trip Time - Time (first part)

We are given that the total trip took 6 hours, and we already calculated the time for the first part as approximately 8.148 hours. Plugging in these values, we get:

Time (second part) = 6 hours - 8.148 hours ≈ -2.148 hours

From the calculation, we can see that the time for the second part of the trip is approximately -2.148 hours. However, this result does not make sense because time cannot be negative. Therefore, there must be an error in the information provided, as it is not possible for Andrea to have traveled at an average speed of 80 kilometers per hour for a positive amount of time and have the total trip take 6 hours.

Distance for second part = x km

Distance for the first part = 440-x km
Total time:
(440-x)/54 + x/80 = 6 hours.
Solve for x.
