susan is driving to mount shasta .on her map she is a distance of 7 inches away .the scale of the map is 1/2 inch=50 miles.how far must susan travel to reach her destination?

Answer 1

700 miles

Explanation:

Given:

Scale of the map is
`(1)/(2)\textrm{ in}=50\textrm{ mi}`

∴
`1\textrm{ in}= (50)/((1)/(2))=50* 2=100\textrm{ mi}`

Distance of Susan from mount Shasha on the map is 7 inch.

Therefore, Number of miles =
`7* 100=700\textrm{ mi}`

Hence, Susan must travel 700 miles to reach her destination.
