ty mam:)

could’nt get 6 question…. anyone plz elaborate

each of the three small pump works at 2/3 the rate of the large pump.

then Work by three small pumps = Work by two large pumps

All 4 pumps = Three small pumps(2 large pump)+ One large pump = Three large pumps

All 4 pumps / 1 large pump alone = 3/1==> time 1/3

tnks a tonn!!

answer for 2nd question is wrong

=80/[(20/10)+(20/20)+(20/30)+(20/40)]

=80/(2+1+2/3+1/2)

=80/([12+6+4+3]/6)==>80*6/25=19.2km/hr

One other thing is the fact individual states in the United states of america have their unique laws in which affect people, which makes it extremely tough for the our elected representatives to come up with a different set of recommendations concerning home foreclosure on people. The problem is that a state possesses own laws and regulations which may have impact in an unfavorable manner in regards to foreclosure procedures.

Howdy! I know this is kinda off topic but I was wondering
