@ktnguyen1 right here man!

Answer 3

60?

Answer 4

Let r be Alexis' speed. Then r-10 is Ravi's speed.
Speed times Time = Distance. Refer to the equation below:
\[3r+3(r-10)=380-1(r-10)\]
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.
So, Alexis' speed, = 60 mph.
