FillingTime=0.4 [hours]

Both pumps take 0.4 hours to fill the tank, or 24 minutes.

Explanation:

First lets calculate the pumping ratio of each pump, assuming V as the volume of the tank:

Pump A:

2 hours to fill the tank, so the ratio will be

$Ratio_{A} =\frac{Volume}{Time} =\frac{V}{2}[\frac{liters}{hours}]$

Pump B:

1/2 hour to fill the tank, so the ratio will be

$Ratio_{B} =\frac{Volume}{Time} =\frac{V}{1/2}=2V [\frac{liters}{hours}]$

So, to fill the tank with both pumps at the same time we sum both ratios to have the total filling ratio

$Ratio_{A+B} =\frac{V}{2} +2V=2.5V [\frac{liters}{hours}]$

Finally we have to calculate how much time takes to fill the tank of volume V with the new ratio:

$FillingTime=\frac{Volume [liters]}{FillingRatio[\frac{liters}{hours} ]} =\frac{V [liters]} {2.5V[\frac{liters}{hours} ]}=\frac{1}{2.5} [hours]=0.4 [hours]$
