As a block of ice melts, its weight changes from 1 /34 lb to 1/4 lb. This change takes 1/4 h. The ice melts at a constant rate.

At what rate does the weight of the ice change? Show your work.
PLZ HELP ME?!?!?

You must have these backwards as 1/34 lb is less than 1/4 lb. finding a common denominator, we get (17/68 - 2/68)/(1/4) = 60/68 = 15/17 lb/hour
