3 min 15 second = 3.25 min

Tap A take x min to fill the tank
x min ↣ 1 tank
3.25 min ↣ 3.25/x tank

Does that mean 3.25/x is the time taken for tap A to fill the tank with some water

3.25/x+5 is the time taken for tap b to fill the same tank with some water

Yes. You're right.
Mean for 3.25 min, for example
Tap A filled 3/5 of tank and
Tap B filled 2/5 of tank
So, total Tap A And Tap B filled full tank in 3.25min

In short, calculate tank height in 3.25min
