Here is the answer and steps. Answer:-3/5
If i understand the question correctly the plane will fly 6 trips of 500 miles each trip.
Number of minutes it takes the plane to fly 500 miles
= 500 / 11
= 45.45 minutes
For 6 trips this = 45.45 * 6 = 272.73 minutes
= 4.55 hours to nearest hundredth.
Step-by-step explanation:
1. d = rt
Divide t from both sides.

2. PV = nRT
Divide P from both sides.

3. 
Add g to both sides.
= g + a
Now multiply by 2 on both sides.
x = 2(g + a)
(or, x = 2g + 2a)
4. g
Divide g from both sides.

Now subtract 1.5 from both sides.
h = 
5.
n = 
Let b be the base. Then
b+16=1/2 (6b)
3b=b+16
2b=16
b=8
