"74 miles away"; from her house??

You want what?
x, time having ridden away
y, distance from her house
assuming this travel is in one direction
POINTS (2,18) and (9,74)

y-18=%28%2874-18%29%2F%289-2%29%29%28x-2%29
y-18=8%28x-2%29
y=18%2B8x-16
highlight%28y=8x%2B2%29

She rides at 8 miles per hour, and she is already 2 miles from her house when she begins riding.

The post is incomplete and the question is absent.

Any discussions would be counter-productive.

        I said  " any discussion ",  meaning that discussion
        in the post by @josgarithmetic, in the first turn.
