Question

Triangle $ABC$ has side lengths $AB=5$, $BC=6$, and $AC=7$. Two bugs start simultaneously from $A$ and crawl along the perimeter of the triangle in opposite directions at the same speed. They meet at point $D$. What is $BD$?

Answer 1

Answer:

4

Step-by-step explanation:

Let the value of BD be x.

Therefore, CD=6 - BD=6-x

As, speed is same, so the distance will be equal

Thus, 5+x=7+(6-x)

x=4

BD=4
