Answer :
Indy and kokomo will be 60 miles apart in real life.
Explanation
On the map, Indy and ft. Wayne are 3 cm apart and Kokomo and Indy are 1.5 cm apart.
So, the ratio of the distance between Indy and ft. Wayne to the distance between Kokomo and Indy will be: [tex]3: 1.5 = 30:15= 2:1[/tex]
Now, lets assume that real distance between Indy and ft. Wayne is [tex]2x[/tex] cm and real distance between Kokomo and Indy is [tex]x[/tex] cm.
Given that, the real distance between Indy and ft. Wayne is 120 miles.
That means....
[tex]2x= 120\\ \\ x= \frac{120}{2}=60[/tex]
So, Indy and kokomo will be 60 miles apart in real life.
