Best ResponseYou've already chosen the best response.0In this equation, we know that if y increases, x decreases and vice versa

Best ResponseYou've already chosen the best response.0The time it takes to erect a bonfire is inversely proportional to the number of students doing the work. If it takes 20 students 1.5 hours to do the job, how long will it take 35 students to do the job, to the nearest minute?

Best ResponseYou've already chosen the best response.1okay equation for inverse variation is y =k/x <(y inversely proportional to x) read the question **time it takes to erect a bonfire is inversely proportional to the number of students** time inversely proportional to number of students let time = t students = S so equation would be \[\huge\rm t =\frac{ k }{ s }\]

Best ResponseYou've already chosen the best response.1when t =1.5 s=20 so plug in t and s value solve for k (constant of variation)

Best ResponseYou've already chosen the best response.1that's k you need y value when =35 so now use the same equation solve for y

Best ResponseYou've already chosen the best response.1***to the nearest minute*** so 60 sec in a mint multiply that by 60
