Astudent walks 144 m west, then turns around and walks 89 m east. if this takes place in a 7.5- minute interval, what is the students average velocity in meters per second? what is the students average speed?

Ohm's law tells you that i = v/r where v is equivalent voltage and r is equivalent resistance of the circuit
since all circuits have the same voltage, your question is really asking which circuit has the lowest total resistance, since the lower the resistance, the higher the current
circuit a has a resistance of 5 ohms; circuit c is in series so has a resistance of 10 ohms; circuit b is in parallel and therefore has a resistance of 2.5 ohms (review your notes on adding resistances in parallel and series); therefore b has the highest current

Ibelieve the answer is either b or c, but i'm leaning more towards c.hope my answer has you : )

What the heck r u talkin bout? ?
