Write down an expression, in terms of
for the number of minutes taken by Pump A
to fill the tank completely
Pump B can fill water into the tank at a rate of

for the number of minutes taken by Pump B
to fill the tank completely.
(iii) If Pump A takes 30 seconds longer than Pump B
to fill the tank completely, formulate an equation
in x to represent this information and show that
it reduces to x + 50:- 150 000 =0.
(iv) Solve the equation x + 50x - 150000 =0, giving
both your answers correct to 2 decimal places,
(v) Find the time taken for Pump B to fill the tank
