My question:
I want a solution that applies it with this equation D=RT. Not a repetition of the test explanation pls.
Moreover, is there a difference here between Average speed and speed?

Av. speed = Total Distance/ Total Time
Speed = Distance/Time
Plz refer the link :: https://gmatclub.com/forum/average-speed-on-gmat-140271.html

Iam not sure what repetition you are mentioning . But, this question is a relative speed ques and even you use D = ST , it boils down to same the formula/principle of relative speed
Let time = T
Distance travelled by Marcus = 207T
and Distance travelled by James = 217T
Now,
The time taken by James to lead Markus by one lap is:: 217T - 210T = 25
or 10 T = 25
or T = 2.5 hrs
