The correct answer is A.
That is because the whole paragraph talks about a model car that they are testing but this student is wondering about roller coasters.
Hope this helps :)
Answer: 60 miles
Step-by-step explanation:
Given
It takes ferry 2 hours to travel to town A and only 
to travel back to town B.
Speed of current is 
Suppose the speed of the ferry is 
mph
Distance traveled in both the cases is same, but it took more time traveling to city A that is, ferry is moving upstream and downstream for returning time.
Distance between the towns is 
The answers to that problem vary which one came fiat
If the gradient is -2 that just means we work back the way, the method i use to find the gradient is y^2-y^1/x^2-x^1 so if we sub the variables in that gives us -18-(-8)/3-x so if we add that up we get -10/3-x, so what has to be on the bottom to get -2? in this case it would be -2 so the overall answer would be -10/5 which would give us a slope of -2 when simplified :) hope this helps
