D=RT
90=(X+2X)2
90=3X*2
90=6X
X=90/6
X=15 MPH FOR THE SLOWER CYCLIST.
2*15=30 MPH FOR THE FASTER CYCLIST.
PROOF;
90=(15+30)2
90=45*2
90=90

Just to show a small illustration here where the two Cyclists are:
We know Distance Formula = Speed x time
Both covered the Distance of 90miles in 2 hours:
*note: , Cyclist[1] is twice as fast Cyclist[2]
--->
, Speed of
Also,
, Speed of
Check,
Thank you,
