Question

On a map drawn to scale 1/2 inch =200 miles, what is the distance in miles between two cities that are 3*1/2 inches apart on the map?

A) 300 B) 350 C) 700 D) 1200 E) 1400

Can anyone help me with this math with explanation?

Answer 1

E

there are 7
`(1)/(2)`'s in 3
`(1)/(2)`

Hence the distance between 2 cities = 7 × 200 = 1400 miles

Answer 2

There are 7 one-halves in 3 1/2, so multiply 200 by 7:

E) 1400 is the correct answer
