Charles DATA:
rate = 49 mph; time = x hrs ; distance = 49x miles
----------------------------
Samantha DATA:
rate = 51 mph; time = (x-24/60) ; distance = 51x - 20.4 miles
---------------------
Equation:
distance = distance
49x = 51x-20.4
-2x = -20.4
x = 10.2 hrs
----
x-(24/60) = 10.2-0.4 = 9.8 hrs = 9 hrs 48 minutes
