distance = rate * time or rate=distance/time or time=distance/rate
==
The deisel train catches up to the cattle train. That means they travel the same distance at that instance.
--
The distance travelled by the deisel train: d=r*t=45mph*4hours=180 miles
It also means that the cattle train travel 180 miles when they were together.
--
But the cattle train had travelled for an additional 14 hours or a total of 14+4 =18 hours
--
Cattle rate (or speed)=d/t=180miles/18hours=10mph

A cattle train left Miami and traveled toward New York.
14 hours later a diesel train left traveling at 45 km/h in an effort to catch up to the cattle train.
After traveling for four hours the diesel train finally caught up.
What was the cattle trains average speed?
:
Let s = cattle train speed
:
The cattle train will be traveling 14 + 4 = 18hrs when the diesel catches up
:
When the diesel overtakes the cattle, they will have traveled the same distance
Write a distance equation; dist = speed * time
:
Cattle dist = diesel dist
18s = 4*45
18s = 180
s = 10 kmh is the cattle train
:
Both travel 180 km
