Choice K
$50 \times \frac{m i l e s}{h o u r} = 50 \times \frac{m i l e s}{60 m i n u t e s} = \frac{5}{6} \times \frac{m i l e s}{m i n u t e}$ $\Rightarrow 120 m i l e s \div (\frac{5}{6} \times \frac{m i l e s}{m i n u t e}) = 120 m i l e s \times (\frac{6}{5} \times \frac{m i n u t e}{m i l e s}) = 144 m i n u t e s$
