Question

^{....scot left the mall and drove towrd the ferry office at an avridge speed of 50 mphsometime later emily left driving the oposite direction with an average speed of 45 mph after scott had driven for 5 hrs they were 430 miles apart how long did emily drive}

 

Answer 1

50•5 + 45(5 - x) = 430

250 + 225 - 45x = 430

          475 - 45x = 430

                 -45x  = -45

                      x  =    1

 

Therefore, Emily drove 5-1 = 4 hours.
