I have put this together but I am unable to figure out how to do it (I know I am wrong/missing something)
R+D=T
R+49 = R+77
R - R = 28 mph
= 28mph (but this leaves 'nothing' on the left side of the equals sign) Found 2 solutions by Fombitz, MathTherapy:Answer by Fombitz(32388) (Show Source):
You can put this solution on YOUR website! You need another equation.
You're solving for rate, current, and time but you only have two equations,
You can get,
and
But you can't solve for all three.
