An aircraft travels with the wind for 120 miles in 0.75 of an hour. the return trip is flown against the wind and takes exactly 1 hour. which system of linear equations represents x, the speed of the plane in miles per hour, and y, the speed of the wind in miles per hour? recall the formula d = rt. 0.75(x + y) = 120 x − y = 120 0.75(x − y)= 120 x + y = 120 120(x + y) = 0.75 120(x − y) = 1 120(x − y) = 0.75 120(x + y) = 1

120 = (x+y)0.75

120 = x - y

Step-by-step explanation:

Given in the question,

Suppose speed of aircraft = x

               speed of wind = y

Traveling with the wind, the total speed of aircraft = x + y

Traveling without the wind, the total speed of aircraft = x - y

Formula to use

120 = (x+y)0.75

Return trip

120 = (x-y)(1)

120 = x - y

After solving the two equations simultaneously

with wind speed = 160 mph

without wind speed = 120 mph

step-by-step explanation:

the options are kind of confusing. i can tell you what i see going on here when i look at the graph.

the class and exam medians are closely related, and it looks like the low outlier on the exam did pull the median lower. [tex][/tex]
