For one washer you must include the waste and the width so.. (3/32)+(1/16)=5/32 or 0.15625 You have 25.5 inches of pipe so how many washers can be taken from it.. 25.5/0.15625=163.2 Rounding to the lower number as it will only make .2 of the 164th washer
After a half hour a third will go.. 216x1/3=72 (go) 216-72=144 remaining after half hour From the remaining 144, another third will go 144x1/3=48 (go in the second half hour=after an hour) 144-48=96 (left after an hour) Therefore answer is d -96
