Answer:
They are 240 kilometers apart.
Step-by-step explanation:
This question can be solved using the following relation:

In which v is the velocity, d is the distance and t is the time.
An express train travels 80km/h from Ironton to Wildwood.
Here we have
. So



A local train, traveling at 48km/h, takes 2 hours longer for the same trip.
This means that when ![v = 48, t = x + 2[tex]. So[tex]v = \frac{d}{t}](https://tex.z-dn.net/?f=v%20%3D%2048%2C%20t%20%3D%20x%20%2B%202%5Btex%5D.%20So%3C%2Fp%3E%3Cp%3E%5Btex%5Dv%20%3D%20%5Cfrac%7Bd%7D%7Bt%7D)

Since 

Applying cross multiplication





So the distance is:

They are 240 kilometers apart.
It’s is 1

Answer:
Three x negative four
Answer:
Correct choice is D
Step-by-step explanation:
A conditional statement, symbolized by
is an if-then statement in which p is a <u>hypothesis</u> and q is a <u>conclusion</u>.
Given statement: "Stars have ten vertices", consider statements:
p="A figure is a star",
q="A figure has 10 vertices".
Then the conditional statement
sounds as "If a figure is a star, then it has ten vertices."
