A river flows with a steady speed v. A student swims upstream a distance d and then back to the starting point.The student can swim at speed c in still water. a) In terms of d,v, and c what time interval is required for the round tip? [I put L/(dv) + L/(d+v) + L/c dont know if that's correct] b) What time interval would be required if the water were still? Use any variable or symbol stated above necessary. c) Which time interval is larger: swimmng in still water, it will vary, simming with and against the current

Best ResponseYou've already chosen the best response.0Swimming with and against the current is ALWAYS longer because of the extra time required to swim against it, the total average speed of the swimmer (swiming with+against) is slower then the swimmer just swimming in still water
