Answer:
The meaning of the y-intercept is the time needed for the plane to cover 2,000 kilometers at a a speed of 900 kilometers per hour (kph) with no wind.
Step-by-step explanation:
The time it takes the plane to travel 2,000 kilometers with the tailwind, t(x), is defined by the function
[tex]t(x)=\dfrac{2,000}{900}+x,[/tex]
where x is the increase in speed when the plane travels with the wind (tailwind).
The y-intercept is at x = 0, then
[tex]t(0)=\dfrac{2,000}{900}+x\\ \\t(0)=\dfrac{20}{9}=2 \dfrac{2}{9}\ hours[/tex]
The meaning of [tex]2 \dfrac{2}{9}[/tex] hours is the time needed for the plane to cover 2,000 kilometers at a a speed of 900 kilometers per hour (kph) with no wind.
