Answer:
The scale used on his map is 150 miles : 2 inches.
Step-by-step explanation:
Given:
Ted knows the actual distance between two cities is 150 miles. His map shows a distance of 2 inches between these cities.
Now, to find the scale Ted used on his map.
The actual distance Ted know between two cities = 150 miles.
The distance on map between these cities = 2 inches.
So, to get the scale used on his map:
[tex]\frac{The\ actual\ distance\ Ted\ know\ between\ two\ cities}{The\ distance\ on\ map\ between\ these\ cities}[/tex]
[tex]=\frac{150\ miles}{2\ inches}[/tex]
[tex]=150\ miles:2\ inches.[/tex]
Therefore, the scale used on his map is 150 miles : 2 inches.
