Problem
A tap discharges water at a constant rate. The relationship between the time of flow t minutes and the volume of water collected is given by the equation 7.5t=225, where the volume is measured in litres.
(a) What does the coefficient 7.5 represent in this context?
(b) Solve the equation to find the time t required to collect 225 litres of water.
(c) Verify your answer by substituting the obtained value of t back into the equation.
