at a maximum speed an airplane travels 2100 miles against the wind in 6 hours. Flying with the wind, the plane travel the same d
istance in 4 hours. what is the speed of the plane with no wind?
1 answer:
<span><span>Let x be the maximum speed of the plane and y be the speed of the wind
***Note: D = r*t or r = D/t***
x +y = 525mph |2100mi/4hr = 525mph
x -y = 350mph |2100mi/6hr = 350mph
2x = 875
x = 437.5mph, speed of plane. Wind speed is 87.5

Answer:
Answer is 10 degrees Celsius.
Step-by-step explanation:
The x value or Fahrenheit is 50 at the same spot the y value is 10
Since y must equal both 3x+2 and x-4, we deduce that 3x+2 and x-4 must equal each other. So, we have
x = 6
AB = 11
BC = 22
