on a map that is drawn to scale 9 inches represents a distance of d miles. What represents d + 1 miles on the map

3 answers

d miles correspond with 9 inches on the map
so 1 mile corresponds to 9/d inches
d+1 miles corresponds to (9/d)(d+1) inches on the map

doodle with (9/d)(d+1) any way you want.

x = 9(d+1)
-------
d

X equals:

9(d+1)
------
d
