Answer 1

1.2 miles can be expressed as inches by the following:

 

(1.2 miles) (5280 ft/mile) (12 in/ft) = 76,032

 

Expressing this answer with 2 significant figures in scientific notation would look like this: 

 

                         7.60 x 10^4 inches

 

Therefore, 1.2 miles equals 7.60 x10^4 inches
