Answer:
The speed of the jet in still air is 415 mph and the speed of the wind is 19 mph
Step-by-step explanation:
we know that
The speed is equal to divide the distance by the time
Let
x -----> the speed of the wind in miles per hour
y ----> the speed of the jet in still air in miles per hour
we know that
<em>With a tailwind</em>
----> equation A
<em>With a headwind</em>
----> equation B
solve the system of equations A and B by elimination
Adds equation A and equation B
<em>Find the value of x</em>
therefore
The speed of the jet in still air is 415 mph and the speed of the wind is 19 mph
