after 2 minutes she is 1.4 miles from home

after 12 minutes she is 0.9 miles from home

this means that in 10 minutes of walking she traveled 0.5 miles

0.5 miles/10 minutes=5 miles/100 minutes

5 miles/100 minutes=1 mile /20 minutes

1 mile/20 minutes=1/20 of a mile per minute is her rate

after 2 minutes she walked 1/10 mile and is 1.4 miles from home so the distance between homes is 1.5 miles

after 12 minutes she walked 12/20=6/10 miles and is 0.9 miles from home, 0.6+0.9=1.5 miles again
