Atrain goes at a constant speed. if it covers 150 miles in 2 1/2 hours, what distance would it cover in 3 hours?

I think it would cover 180 but i am not 100 percent sure

its a straight line parallel to the time axis

the image is given below

since the options are not given so we draw it from the equation

the given equation is

y = (x-1) (x+4)

y = y² + 3x - 4

the above equation is a quadratic equation which will have two roots. if we draw the graph for it, it will look like this
