Hi,

Re TY, Good Luck to You! 

The toughest part of most word Problems is assigning that first variable!

For Myself, use the example of just getting that done as the step.

One plane travels 65km/h slower than the other traveling at 

D = rt 

 2hr(r-65) + 2hr(r) = 3438mi

    4r = 3568

     r = 892 mph and the other rate is 827mph

 CHECKING our Answer***

 2hr· 892mph + 2hr· 827mph = 3438mi

 3438=r*2

divide both sides by 2

= 1719

r1+r2=r1-65

r1+r1-65=1719

Add 65 to both sides

2r1=1784

Divide both sides by 2

r1=892

r2=892-65=827

Check it:  892+827= 1719
