Question

a map has a scale on it which 3in represents 50 miles use information to match each map distance on the left to the number of miles to distant represent on the right

Answer 1

It is given that the scale used in the map is,

`3\text{ in}\equiv50\text{ miles}`

For 9 inches,

`9\text{ inches=3}*(\text{3 inches)}\equiv\text{3}*(\text{50 miles)}=150\text{ miles}`

Thus, a distance of 9 inches on the map corresponds to 150 miles in actual.

For 15 inches,

`15\text{ inches=5}*(\text{3 inches)}\equiv5*(\text{50 miles)}=250\text{ miles}`

Thus, a distance of 15 inches on the map corresponds to 250 miles in actual.

For 21 inches,

`21\text{ inches=7}*(\text{3 inches)}\equiv7*(\text{50 miles)}=350\text{ miles}`

Thus, a distance of 21 inches on the map corresponds to 350 miles in actual.
