what if i used the CLM eqn with the speeds as V1 and V2 and formed equations in terms of V1 and V2; then made V2 the subject (in terms of V1) then
used V1 - V2 = 1 and substituted the terms from my equation to find V1,
then substituted the V1 value into the eqn to find the value of V2? 😅

Why the speed of B is going to be higher?
