1 answer:
After 0 hours the train has travelled 90 miles from the station.
After 1 hour the train has travelled 135 miles from the station.
This means the train has travelled 135 - 90 = 45 miles in 1 hour.
Therefore the correct answer is A. 45 mph, because speed is the rate of change of distance.

this is my answer but it's on you if you think this answer is correct or wrong
1/2 ; you must look at rise over run. It goes up by one, runs over 2. 1/2 is a half
The answer is 14.4 because you divide 36 and 2.5 and that’s what you would get
when x =1 , y = 3
when x = 3, y =27
27-3 = 24
3-1 = 2
24/2 = 12
rate of change = 12
