The speed of Old Steamy train = 6.14 mph

miles
Now we get that Chug-a-Lug was 290 miles behind the Old steamy.
To know the distance traveled by Chug-a-Lug, we will add distance traveled by Old Steamy to the station plus the distance between the trains.
So, distance traveled by Chug-a-Lug =
miles
The speed of Chug-a-Lug =

=
mph
