time take to fill the tank varies inversely as the area of the cross section of the pipe.the time taken is 40 min wen the area of the inlet pipe is 3cm^2
water flowed into an empty tank thru a pipe of area of 4m^2
it flowed for 9 min.
find in its simplest form, the fraction of the tank that now contained water
plz explain

yes its 3/10 . wil u plz explain that how u rchd that answer?
dekho
t is inversely proportionl to area
so T= k /A
40=k/3
k=120 (constant)

now Area is 4 so time should be
T=120/4 = 30mins
lekin usne sirf 9 mins chalaya to to kitna container full hoga. ??
9/30 = 3/10
