if mr brown leaves 3.5 hours before ms brown and mr brown travels at 65 mph while ms brown travels at 90 mph how long before ms brown overtakes mr brown?
--------
Mr. Brown DATA:
rate = 65 mph ; time = x hrs ; distance = 65x miles
--------
Ms. Brown DATA:
rate = 90 mph ; time = x-3 hrs ; distance = 90(x-3) miles
--------
Equation:
65x = 90(x-3)
65x = 90x - 270
25x = 270
x = 10.8 hrs = 10 hrs 48 minutes
