1 QUESTION URGENT - MAX POINTS! Water flows down a stream at a rate of 7.5 litres/s

b) Calculate how long it takes for 1 m^3/h to flow past a particular point.
rate of m^3/h = 27

can you rephrase the question ? it is unclear : -)

step-by-step explanation:

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4
