What is drift in river boat problems?Is it velocity of river divided by time taken o reach the point aimed?Or velocity of river-countering velocity of swimmer or boat in the direction of boat velocity divided by time taken o reach the point aimed?In the below video ,
although the accent is really hard to understand I found content quite good.So I was watching this but I encountered this doubt.
While calculating drift at time 17:45 he took velocity as rivers velocity-it's countering velocity multiplied by time
but in other problems such as at time 6:22 in calculation of drift only velocity of river (no countering velocity)multiplied by time is taken .Why?
I think it is just a mistake.That's why I will not be able to show any effort.But if you find that it's correct,just give me a hint so that I can clear my doubt on my own.
