Recall that if two triangles are similar, the lengths of corresponding altitudes are proportional to the lengths of corresponding sides.

Let's begin with recalling one of the Special Segments of Similar Triangles Theorems.
If two triangles are similar, the lengths of corresponding altitudes are proportional to the lengths of corresponding sides.
Now, let's look at the given diagram. Let x be the distance between the intersection of the roads and the bank.
We can create a proportion using the fact that the lengths of corresponding altitudes are proportional to the lengths of corresponding sides.
x/50=382/248
Now, we will solve the proportion for x using cross multiplication.
