The rate of the jet stream is 100 miles per hour. Traveling with the jet stream, an airplane can fly 1200 miles in the same amount of time as it takes to fly 1000 miles against the jet stream. What is the airplane's average rate in calm air?

x = 600 mph

Step-by-step explanation:

It is given that,

Speed of the jet stream = 100 mph

It travels 1200 miles in the same amount of time as it takes to fly 1000 miles against the jet stream.

We need to find the airplane's average rate in calm air. Let it is equal to x mph.

As time in same in both cases. ATQ,

So, the airplane's average rate in calm air is 600 mph. Hence, this is the required solution.

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)
