Problem Solving (PS) | Re: Two buses P and Q start from cities A and B towards each other. They m

Seems to me that chetan2u has the shortest method. You have to think about it differently, but I like how quick you can get an answer. I solved a little longer method.

We know that d=r*t. We can assign Rp as rate for P and Rq as rate for Q. We also know that meet at first at one time, call it T1, and then meet again at another time, call it T2.

At the first meeting point 22=Rq*T1 and d-22=Rp*T1.
I solved each for T1 and then substituted for T1 to get 22/Rq = (d-22)/Rp....I

At the second
