You can put this solution on YOUR website! If car A is going 45 mph and car B is driving 35 mph and they both drive 10 miles how much longer does it take Car B to get there?
-----
Car A DATA:
rate = 45 mph ; distance = 10 miles ; time = d/r = 10/45 = 2/9 hr
----
Car B DATA:
rate = 35 mph ; distance = 10 miles ; time = d/r = 10/35 = 2/7 hr
------
Equation:
B time - A time
----
Ans:: 2/7 - 2/9 = (18-14)/(63) = 4/63 hr = (4/63)60 min = 3 min 59 sec
