Answer:

13 and three-fourths inches

Explanation:

The map distance can be found using a proportion with the map scale.

__

map distance / (1100 mi) = (1 in) / (80 mi)

map distance = (1100×1)/80 in = 13 3/4 in . . . multiply by 1100 mi; cancel mi

The trip will be about 13 3/4 inches on the map.
