The solution Of the problem Of the leak
ing boat dependa on q consideration Of two
facts which b the ordinary mind nos
trained n think are entirely unrelated.
The trick IN the question u IN the Inn
plioation that the plug was not replaced
until the boat had BEEN pumped out, Whlqh
"a one correspondent says. y good math-
ematios but poor sramanship.
Several reached their answers BY alRe-
bra. but that u quite unnecessary IN thlg
case ID took fhree men one hour 10 hail
the boat out. which IA equal b three hours
work Of one man 70 get rid u the water
IN the boat and The water that was atill
baking on therhailern.
When four men got on the job they did
i in half an hour. which 5 equal 10 two
Hours WORK 81 one man In getting nd
% the same initial amount plus the amount
that would leak IN during the hailng u
half an hour. From this L follows that one
hours ballihg by one man Il equal 70
half an hours leakage, 20 when three
men were hailing the boat must have
been leaking an hour and a half; but when
four men were hailing Il had been leaking
only an hour: In both caaes reckoning
from the time they got 4 clear.
A. the three men hailed for an hour
the boat mus have been leaking for half
an hour before they started. Az The four
mon hailed for half an hour only the boat
must have bon leaking for half an hour
before they began. the answer being half
an hour In each case Nbr the leak.
Another wayot looking az Il. suggested
by Herbert West. Il that u Ne assume that
each man could bad 100 RAllons an hour
the three men bailed 800 gallons. When
the four Got 10 work, hailing only half
an hour. they must have hailed only DO
gallons In that time. The difference then.
100 gallons, Is leakage. and the rate Of
leakage 10 30 gallons an hour. fhen two
Of the three men simply pumped leakage
and L took the third man an hour 70 set
out what was IN the boat when the three
started. 100 gallons. or half an hours
leakage. When tho fourth man helped
him they did the job in half the time.
the two men stin haillng nothiHR but
leakage. which shows that the time 81
leakage before hailing was the sane IN
each case. half an hour.
