A plane travels 2,000 kilometers at a speed of 900 kilometers per hour (kph) with no wind. When a tailwind is present, the
plane's speed increases by x kilometers per hour. The time it takes the plane to travel the same distance with the tailwind,
t(x), is defined by the function (x) = 2.000. What is the meaning of the y-intercept for this function?

A the time it takes the plane to travel without the tailwind

B the speed of the plane when there is no tailwind present

C the minimum amount of time it takes the plane to travel 2,000 km

D the time it takes the plane to travel when the speed is decreased by 900 kph
