Answer:
Velocity of jet in still air is 800mph hour and velocity of wind is 180mph
Step-by-step explanation:
Let the velocity of jet in still air be x miles per hour and velocity of wind be y miles per hour.
#Jet's velocity against jet-stream is:

#Jet's velocity with jet-stream:

#The velocity against jet-stream is x-y and with jet-stream is x+y:

Hence,velocity of jet in still air is 800 mph hour and velocity of wind is 180 mph.
Answer:
X<2
Step-by-step explanation:
2x+4<8
subtract 4 from both sides
2x+4-4<8-4
simplify
2x<4
divide both by 2
2x/2<4/2
x<2
Answer:
7x

Answer:
$182.91
Step-by-step explanation:
136.50 times 0.14 (14%) is 19.11
136.50 times 0.2 (20%) is 27.30
13650+19.11+27.30=182.91
