A plane averaged 800 mph on a trip going east, but only 400 mph on the return trip. The total flying time in both directions was 4.5 hr. What was the one-way distance?

1200 miles.

Step-by-step explanation:

Let d represent one way distance.

We have been given that a plane averaged 800 mph on a trip going east, but only 400 mph on the return trip.

The time taken while going east would be .

The time taken while returning back would be .

Since the total flying time in both directions was 4.5 hr, so we will equate sum of both times with 4.5 as:

Make a common denominator:

Therefore, the one-way distance was 1200 miles.

$650 per month plus utilities

step-by-step explanation:

just based on the info you gave, it would seem more cost effective to rent at $650 per month plus utilities.   if utilities are, in fact, $150 per month, your monthly living costs would be $800 as opposed to the other option of $825.
