Hm i think i can measure 45min with just 1 string.
as a preparation for the measuring: I burn the string and start walking with constant speed(and counting steps) and i walk till its burnt out. now the measuring starts: i multiply the number of steps with 0,75 and start walking back the same speed, and when i reach the new number of steps - 45mins have passed. you do have to walk the same speed all the way but i think humans are capable of that.

I got answer for the 3rd one: you gotta play with one switch , turn it up and turn it down until the bulb in another room would burn off . After the light is the other room stoped turning on and off you switch on the 2nd switch and go the the other room: bulb that is on connected to the 2nd switch , bulb that is hot and and off is poor bulb connected to the 1st switch and bulb that is off and cold connected to the 3rd switch j/k
You can just hold the 1st switch on for some time , than turn it off , switch the 2nd one , go to the other room ... than read the explanation above.
