first tank would take an 2 hour

Second one take an 3

Answer 2

1/2*1/4 = 1/8th of the tank was filled in 15 minutes

so now,

$x( \frac{1}{2} - \frac{1}{3} ) = 1 - \frac{1}{8}$

$\frac{x}{6} = \frac{7}{8}$

$x = \frac{7 \times 6}{8}$

$x = \frac{21}{4}$

$x = 5 \frac{1}{4} \: hours$

ANSWER : 5 HOURS 15 MINUTES
