Jessica is walking home from a friend’s house. after 2 minutes she is 1.4 miles from home. twelve minutes after leaving, she is 0.9 miles from home. what is her rate in miles per hour?

let's say 12 min - 2 mins = 10 mins

and 1.4 mile - 0.9 miles = 0.5 miles

Jessica takes 10 mins to walk a distance of 0.5 miles

=> 10 mins*6 = 60 mins = 1 hour

=> 0.5 miles*6 = 3 miles

her rate is 3 miles per hour

Jessica's rate is 3 miles per hour.
