Answer:
1950
Step-by-step explanation:
If you were 24 in 1974, simply subtract 24 from 1974 to find what year you were born in:
1974-24= 1950
Of course, it may be +/- 1 depending on what month you were born in, and what month it is now!

Scale : 1 inch = 30 miles
So, the ratio between the distance on the map and the real distance is 1:30
When a quantity increase/decrease in a ratio, the other one increase/decrease respectively.
Call the miles we have to go : x
1:30 = 4.5:x
(1x4.5):(30x4.5) = 4.5 : x
4.5 : 135 = 4.5 : x
So, x = 135 => We have to go 135 miles to get to the place we want to go.
