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:
A
Step-by-step explanation:
a^2 + b^2 = c^2
a^2 + 100 = 256
a^2 = 156
a = 12.48
a = 12.5
