Did you solve the diplomat question?

jamesj · Answer

That question is essentially a much easier version of this question.  You will want to understand that question first before you attempt this one.

Let r be Alexis' speed.  Then r-10 is Ravi's speed. 
Speed times Time = Distance.  Refer to the equation below:$$3r+3(r-10)\text{ = }380-1(r-10)$$The LHS is the total distance both moved in 3 hours.
The RHS is the distance remaining after Ravi traveled 1 hour by himself.
Solve the equation for r.
r, Alexis' speed, = 60 mph.
