This is a absolute value word problem that I had trouble with. Could anyone tell me how to solve it?
a rainstorm begins as a drizzle, builds up to a heavy rain, and then drops back to a drizzle. The rate r (in inches per hour) at which it rains is given by the function r=-0.5|t-1|+0.5 where t is the time (in hours). for how long does it rain and when does it rain the hardest?
