Dr hanson sees one patient every 45 minuets if he works for 7 hours per day how many patients does he see in one day

1 hr = 60 minutes, so 7 hrs = (7 * 60) = 420 minutes

doc sees 1 patient every 45 minutesso in 420 minutes (7 hrs), he sees
420/45 = 9.3rounds to 9 patients <==

or u can set it up as a proportion...
1/45 = x / 420...1 patient to 45 min = x patients to 420 min
cross multiply
45x = 420
x = 420/45
x = 9.3thats 9 patients per day <==
