You are a lifeguard and spot a drowning child 30 meters along the shore and 60 meters from the shore to the child. you run along the shore and for a while and then jump into the water and swim from there directly to child. you can run at a rate of 5 meters per second and swim at a rate of 1 meter per second. how far along the shore should you run before jumping into the water in order to save the child? round your answer to three decimal places.

(2) (a) you have a simple circuit that consists of only a battery (δvbat=1.5v) and two resistors with resistance r1=10ω and r2=5ω, connected in series with each other. what is the current running through the battery? (b) you re-arrange your circuit so now r2 is attached in parallel to r1 rather than in series. what is the current running through the battery? (c) you add an additional resistor r3=7ω on the same branch as r2. what is the current running through the battery? (d) what is the power dissipated in r3?
