Answer:
We can use a proportion to solve this problem:
1 inch represents 60 miles
x inches represent 3000 miles
To find x, we can cross-multiply and solve for x:
1 inch * 3000 miles = 60 miles * x inches
3000 = 60x
x = 3000/60
x = 50
Therefore, 50 inches will represent 3000 miles on the map.
So the answer is (b) 50
