Answer:
The real distance from shop to store is 24 kilometers.
Step-by-step explanation:
Given:
Distance from the Bake Stars Cafe to the restaurant supply store on map = 3 cm
Also Given:
Scale of the map 1 cm = 8 km
We need to find the real distance from the shop to the store.
Solution:
Now we know that;
Distance from shop to store on map =3 cm
1 cm = 8 km 
3 cm = Real distance from shop to store
By using Unitary method we get;
Real distance from shop to store = 
Hence The real distance from shop to store is 24 kilometers.
