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

Is that the way I am going to find D?

Sides are proportional

if the above two triangles are similar, that's mean s should be equal to w?

i am confused that how D,d,w can help us calculate s

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.

will it look like this?

will there be 2 lines with different angles? does that mean i will have two diagrams?
