Answer:
water leak is 650 gallons
time required to full drain is 80 hrs
Explanation:
given data
volume V = 3200 gallon
rate = V(t) = 80 - t
to find out
how much water leak between 10 and 20 hour and drain complete
solution
we know here rate is 80 - t
so here rate will be
= 80 - t
and for time 10 and 20 hour
take integrate between 10 and 20
so water leak = .....................1
water leak = ( 80t -
water leak = 650
so water leak is 650 gallons
and
we know here for full tank drain condition
water leak full = 80 t -
3200 = 80 t -
6400 = t² - 160 t
t = 80
so time required to full drain is 80 hrs
