Convert the Map scale into a unit rate. How many Inches represent 1 mile? Show your work. Interpret The meaning of the Unit Rate. 3/10 in. = 7/8 mi

We are given that:

3/10 in = 7/8 mi

Use cross multiplication to get the scale as follows:

3/10 in = 7/8 mi

3 (8) in = 7 (10) mi

24 in = 70 mi

24/70 in = 1 mi

1 mi = 0.3429 in

Therefore:

unit rate of the map is: 1 mi = 0.3429 in

This means that:

each one 1 mile in reality is represented by 0.3429 inches on the map
