An express train travels 80km/h from Ironton to Wildwood. A local train, traveling at 48km/h, takes 2 hours longer for the same
masha68 [24]

Answer:

They are 240 kilometers apart.

Step-by-step explanation:

This question can be solved using the following relation:

v = \frac{d}{t}

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 v = 80, t = x. So

v = \frac{d}{t}

80 = \frac{d}{x}

d = 80x

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}

48 = \frac{d}{x+2}

Since d = 80x

48 = \frac{80x}{x+2}

Applying cross multiplication

80x = 48(x + 2)

80x = 48x + 96

32x = 96

x = \frac{96}{32}

x = 3

So the distance is:

d = 80x = 80*3 = 240

They are 240 kilometers apart.
