Use the distance (d), rate (r), and time (t) relationship.
d+=+r%2At Substitute the given r+=+1%2F%28t%2Ba%29 and t+=+bt%2Bab
d+=+%281%2F%28t%2Ba%29%29%2A%28bt%2Bab%29 Simplify.
d+=+%281%2F%28t%2Ba%29%29%2A%28b%28t%2Ba%29%29
d+=+%281%2Fcross%28%28t%2Ba%29%29%29%2A%28b%2Across%28%28t%2Ba%29%29%29 Cancel the indicated factors.
d+=+b Sonya walked b miles.
