Answer: 210 miles
Step-by-step explanation:
We can convert the fractions into decimals—3 1/2=3.5, and 1/4=.25. We can then divide 3.5/.25, which will give us 14. This tells us that 3 1/2 is comprised of fourteen 1/4 inches. Since 1/4 equals 15 miles on a map, we can just multiply 15 times 14, which gives us 210 miles—that is your answer.
