Answer:
Part 1 .
As per the given statement: In t hours the train has traveled s miles.
Distance of the train = s mile
Time = t hours
Formula for :
Speed of the train(v) = 
or
mph .....[1]
Substitute the value of t = 3 hours and s = 180 miles in [1], to solve for v;

Therefore, the speed of the train(v) is, 60 mph
Part 2.
Similarly,
The formula for speed of the train (v) is given by;

Substitute the value of t = 2.5 hours and s = 225 miles to solve for v;

Therefore, the speed of the train(v) is, 90 mph
