Question 1133136
(a) {{{ t }}} minutes
(b) {{{ v }}} ml
(c) {{{ 60*( t/4 ) }}}
(d) {{{ 100 - 60*( t/4 ) }}}
(e) {{{ v = 100 - 15t }}}
I'll skip to (h)
The bucket runs out of water when {{{ v=0 }}}
{{{ 0 = 100 - 15t }}}
{{{ 15t = 100 }}}
{{{ t = 6 + 2/3 }}} min
and {{{ (2/3)*60 = 40 }}} sec
In 6 min 40 sec the bucket is empty
(i) ( 2,70 ) is {{{ t = 2 }}} min and {{{ q = 70 }}} ml
{{{ 70 = 100 - 15*2 }}}
{{{ 70 = 70 }}}
It is a point on the line
( note: you can draw the line )
