Question

Use a mapscale of 1/2 inch : 10 miles to find the actual distance for each measurement.
1. 5 in. ______________
2. 2 in. ______________
3. 7 in. ______________

Answer 1

1. ) 0.5/10 = 5/x
cross multiply
(.5)(x) = (10)(5)
.5x = 50
x = 100 miles.

2. 0.5/10 = 2/x
cross multiply
(.5)(x) = (10)(2)
.5x = 20
x = 40 miles

3. 0.5/10 = 7/x
cross multiply
(.5)(x) = (10)(7)
.5x = 70
x = 140 miles
