Answer:
Step-by-step explanation:
Given : The outdoor temperature was 8 degrees at midnight.
The time at mid-night is 12AM.
Then , the new cycle of hours starts, after 1 hour time the new time will be 1 AM , after 2 hour the new time will be 2 AM, and after 3 hours from midnight the new time is 3AM.
Since, The temperature declined 5 degrees during each of the next 3 hours.
Then, the temperature at 3 A.M. =
Hence, the temperature at 3 A.M =
Let's assume time taken by plane on one way distance as 't'
The total flying time in both directions was 10.5 hr
so, time taken in other direction =10.5-t
now, we are given
A plane averaged 500 mph on a trip going east
so, total distance of one way is
total distance of other way is
now, we can that distance is same from both sides
so, we get
now, we can solve for t
now, we can find one way distance
miles..............Answer
