The triangle inequality requires the sum of the two short sides exceed the long side.
6 +14 = 20 > 18
The triangle inequality is satisfied by these numbers, so they could be the side lengths of a triangle.
Answer:
4 hours
Step-by-step explanation:
We can already assume that the freight train is 60 miles ahead of the express. If the freight is going at a constant of 30 mph and the express goes 50 mph then we can say that when the freight train has been gone for 6 and the express for 4 the express will have passed the freight. The reason as to why would be that 60 + 120 = 180 or 60 + (30 x 4) = 180 and 50 x 4 = 200 .
Sorry if that explanation doesn't make sense but I hope this helped.
