Rate*Time=Distance
R%2At=D
.
.
.
R%5B1%5D%2At=D%5B1%5D
R%5B2%5D%2At=D%5B2%5D
R%5B1%5D=R%5B2%5D-25
In two hours,
D%5B1%5D%2BD%5B2%5D=470
R%5B1%5D%2A2%2BR%5B2%5D%2A2=470
R%5B1%5D%2BR%5B2%5D=235
Substitute,
%28R%5B2%5D-25%29%2BR%5B2%5D=235
2R%5B2%5D=260
highlight%28R%5B2%5D=130%29mph
.
.
R%5B1%5D=130-25
highlight%28R%5B1%5D=105%29mph
