As per the question, the velocity of the airplane [v] = 660 miles per hour.
The total time taken by airplane [t] = 3.5 hours.
We are asked to determine the total distance travelled by the airplane during that period.
The distance covered [ S] by a body is the product of velocity with the time.
Mathematically distance covered = velocity × total time 
                                                       S = v × t
                                                         = 660 miles/hour ×3.5 hours
                                                         = 2310 miles.
Hence, the total distance travelled by the airplane in 3.5 hour is 2310 miles.

Answer:
C1 + C2 = 30     parallel connection
C1 * C2 / (C1 + C2) = 7.2  series connection
C1 * C2 = 7.2 * (C1 + C2) = 216
C2 + 216 / C2 = 30    using first equation
C2^2 + 216 = 30 C2
C2^2 - 30 C2 + 216 = 0
C2 = 12 or 18    solving the quadratic 
Then C1 = 18 or 12
 
        
             
        
        
        
A=Fh
A - work
F - force
h - distance
F=mg
m - mass (god+basket)
so
A=mgh
187 = m*10*4
187=40m
m=187/40
m=4.675 kg 
or 4kg and 675g

Answer:
The magnitude is "3.8 m/s²", in the upward direction.
Explanation:
The given values are:
Mass,
m = 88 kg
Scale reads,
T = 900 N
As we know,
⇒  
On substituting the given values, we get
⇒      
⇒      
Now,
⇒  
On substituting the given values in the above equation, we get
⇒  
On subtracting "862.4" from both sides, we get
⇒  
⇒              
⇒                   
⇒                    (upward direction)
 (upward direction)
