Correct Answer: 60 km/hr


Solution : The person covers a certain distance in 6 hours if he travels at 40 km/hr.
$\text{Speed}=\frac{\text{Distance}}{{\text{Time}}}$
Distance covered in 6 hours = 6 × 40 = 240 km
$\therefore$ To cover the same distance in 4 hours, then his speed must be $\frac{240}{4}$ = 60 km/hr
Hence, the correct answer is 60 km/hr.
