Question

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?

Answer 1

Answer:

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:

$x = v*t$

Where:

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

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

$x = v*t = 204 mi/h*12 h = 2448 mi$

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

$t = \frac{x}{v} = \frac{2448 mi}{232 mi/h} = 10.6 h$

Therefore, the flight to Portland takes 10.6 hours.

I hope it helps you!
