Answer: 100 miles
Step-by-step explanation: How much time does the bird spend in flight? If you represent the problem in terms of the amount of time the bird is flying, then a solution is fairly straightforward. The two trains are 50 miles apart, and are approaching each other at a relative speed of 50 mph (25 + 25), so it will take one hour for them to meet. If the bird spends one hour flying at 100 mph, then it will traverse 100 miles before the trains meet.

Answer:
2h-3a
Step-by-step explanation:
First Find f(a+h)
f(a+h) =-a-h
Then find f(a)
f(a) =2a-3h
Then f(a+h) - f(a)= - a-h-(2a-3h)=2h-3a
