A plane set off to Portland at a speed of 232 mph. On the return flight of 12 hours, the plane cruised at 204 mph.
How many hours long was the flight to Portland?

The flight to Portland takes 10.6 hours.

Step-by-step explanation:

To find the time of flight to Portland we need to calculate the distance traveled by using the equation:

Where:

v: is the speed = 204 mph (return flight)

t: is the time = 12 h (return flight)

Now, we can find the time of flight to Portland using v = 232 mph:

Therefore, the flight to Portland takes 10.6 hours.
