let 't' be the time you need to water your neighbor's lawn
you can water your 43 foot by 28 foot rectangular lawn in 7 minutes and 20 seconds or
43*28 ft^2 in 7 min 20 sec = 7 20/60 min = 22/3 min
68 foot by 37 foot rectangular lawn is an area of 68*37 ft^2
now we have the following proportion
(43*28) : (22/3) = (68*37) : t
by solving we find
t = 15.32 min
