Solution

The correct option is D $6$ hr $40$ min
Speed of the man=40 km/hr
Didtance=240 km
$T i m e = \frac{d i s t a n c e}{s p e e d}$
$\Rightarrow \frac{240}{40} = 6 h r$
But in 240 km journey man takes rest of 20min after every 80 km
Hence he takes 2 rest and he takes 40 min
Hence the total time to cover the distance is 6 hr 40 min
