1f. - it would be faster to walk home. You heard the subway come 3mins ago so subtract that from 15 = 12 then add the 8mins it takes to ride it = 20 to walk home it would take 15mins because at 4miles per hour you and walk 1 mile in 15mins
1b. - I don't compleatly get this one but it would take 15mins to get to your house at a speed of 4 miles per hour. this is why - 4miles/60mins = 1mile/xmins x=15
1a. - 20 minutes
