The Gomes family is on a road trip. On the first day, they drove a distance shown as 3 1/2 inches on a map. The actual distance that they drove was 245 miles. Which is the scale of the map?
A. 1 in : 3 1/2 mi
B. 1 in : 7 mi
C. 1 in : 70 mi
D. 3 1/2 : 70 mi

Answer 1

1/r = (3 1/2)/245
(3 1/2)r = 245
r = 245/3 1/2
r = 70

scale is 1 in to 70 miles.
