    isn't the formula still the same that speed=distance traveled by car / the time it took to travel that distance if I have the angle I can just use the height and tan(theta) to figure out the distance traveled by car. s/d=tan(θ)

    in that case, we can find S by s/w=D/d we have three things given and we have to find S

    Calculus derivatives word problem

    yeah, I can use the trigonometry but for that other side, I need an angle. I am confused about that angle. part. For the time I will start with 0s and till the time I can see it.
