Charlie and Chang start at the same point and drive in opposite directions. Charlie drives 44 mph and Chang drives 46 mph. How far apart will they be in 2 hours? Distance = rate x time Charlie D = rt {distance = rate x time} D = 44(2) {substituted given information into distance formula} D = 88 miles {multiplied} Chang D = rt {distance = rate x time} D = 46(2) {substituted given information into distance formula} D = 92 miles {multiplied} Charlie and Chang's combined distance = 88 + 92 {added the distances, they are driving in opposite directions} = 180 miles {added}  Algebra House
