Can u plz help me with this question step by step

Answer 1

Step-by-step explanation:

Let the quantity of tank be 16ltrs.

P1 takes 4 hrs to fill it

So, it fills 4ltrs per hour

P2 takes 8 hrs to fill it

So, it fills 2ltrs per hour

If both are opened simultaneously, they will fill 6ltrs per hour

So, 16ltrs of tank will be filled in 16/6hrs i.e., 2hrs40mins
