Question 982489: At a given, car a and car b are running in the same directions. Car a runs 65 1/2 km/hr and car b runs 57 3/4 km/hr. How far apart will they be after 2 1/2 hours? Answer by macston(5194) (Show Source):

If they start at the same time from the same point in the same direction, the distance between them is the difference in rates time times time:
.
(65.5km/hr-57.75km/hr)(2.5hrs)=19.375 km
.
CHECK:
CAR A: (2.5 hrs)(65.5 km/hr)=163.75km
Car B: (2.5 hrs)(57.75km/hr)=144.375km
163.75-144.375=19.375km
