4plumbers +5helpers =182
5plumbers +6helpers =224
-24plumbers -30helpers =1092
25plumbers+30helpers =1120
1plumbers =28
4.28+5helpers =182
5helpers =70
1helpers=14
Given that the time taken to get to campus is inversely proportional to driving rate, let the time be t and rate be r, thus the function will be written as:'
t=k/r
where
k is the constant of proportionality given by:
k=tr
when r=20 mph, t=1.25 hrs
thus
k=20×1.25
k=25 miles
thus the formula is:
t=25/r
when r=55 mph, the value of t will be:
t=25/55
t=5/11 hours
Yes because each x value differ by 2.5 and each y value also differs at aconstant rat of 1
