Step-by-step explanation:</h3>
In order for three line segments to form a triangle with non-zero area, they must satisfy the "triangle inequality." There are several ways to express this, but perhaps the simplest is ...
a + b > c
where a, b, and c are the lengths of sides in order from shortest to longest.
Here, that means the requirement for a triangle is ...
4 + 4 > 7 . . . . true, so <em>a triangle can be formed</em>
The triangle inequality is satisfied by these segment lengths.
3344=42=23-31=31-31342333333333333
The combined speed are 47 + 50 = 97 mph
required number of hours = 388/97 = 4 hours
