Let t=time it takes for the freight train to make the trip
t-2=time it takes for the passenger train to make the same trip
Since distance=speed*time, and the trains traveled the same distance, we get:
96*(t-2)=64*t
Simplifying...
96t-192=64t
Subtracting 64t from both sides, we get:
32t-192=0
Adding 192 to both sides, we get:
32t=192
Dividing both sides by 32 we get:
t=6 (6 hours for the freight train to make the trip)
To get the distance, (using the distance=speed*time formula)
distance = 64 * 6 = 384 miles
Central City to Clear Creek is 384 miles
