Answer 2

Answer:

Let x = speed of the cattle train

:

Write a distance equation; dist = speed * time

:

we know when the two trains will have traveled the same distance.

:

We know from the given information that the cattle train will have been traveling for 14 + 4 = 18 hrs

:

Cattle dist = diesel dist

18x = 4*45

:

18x = 180

x = 

x = 10 mph is the speed of the cattle train

:

:

Check the solution by finding the distance of each:

18 * 10 = 180 mi

4 * 45 = 180 mi
