The fastest land vehicle ever manufactured to date is the Sonic Wind LSRV, which is being prepared to reach a speed of $3000 \mathrm{~km}/\mathrm{h}$. It is faster than the Concorde, one of the fastest passenger aircraft ever made, which reaches $2330 \mathrm{~km}/\mathrm{h}$.
For a fixed distance, speed and time are inversely proportional.
To cover a distance of 1000 km, the value closest to the difference, in minutes, between the times spent by the Sonic Wind LSRV and the Concorde, at their maximum speeds, is
(A) 0.1.
(B) 0.7.
(C) 6.0.
(D) 11.2.
(E) 40.2.
