time = distance / speed time = 279/62 time = 4.5 hrs...or (4 hrs 30 minutes)
plus they plan on a 45 minute lunch... 4 hrs and 30 minutes + 45 minutes = 4 hrs and 75 minutes = 5 hrs 15 minutes. So they need 5 hrs and 15 minutes to get there...and they want to be there by 3.
There is 16 ounces in 1 pound. so you would want to divide 12.40 by 5 = $2.48 . so its $2.48 for a pound divide by 2 and you answer would be $1.24... i hope that helps
