A car leaves town traveling at 40 mi/hr. Two hours later, a second car leaves the same town, on the same road traveling 60 mi/hr. In how many hours will the second car pass the first car? use formula d=rt. write equation and solve. Be sure to define variable
-----
1st car DATA:
rate = 40 mph ; time = x hrs ; distance = 40x miles
--------
2nd car DATA:
rate = 60 mph ; time = x-2 hrs ; distance = 60(x-2) miles
------
Equation:
distance = distance
40x = 60x - 120
20x = 120
x = 6 hrs
