set up a proportion
first find out how many degrees the temperature needs to rise
yes sorry, i'm working it out now and will show you if itsc orrect
ok soi did it like this...
the final temperature is 37, but we start at 20. so how many degrees does it need to increase by?
(hint: replace "37" with "37-20" in your proportion and solve for x)

so an 1hr and 42 min
uh, not quite.
yes i got 85 minutes
right, and 85 minutes = 1 hr and 25 minutes
(there are 60 minutes in one hour)
