In a car race, a driver covered three sections: one of $240 \text{ km}$, one of $300 \text{ km}$, and one of $400 \text{ km}$. The driver knows that the average speeds in these sections were $40 \text{ km/h}$, $75 \text{ km/h}$, and $80 \text{ km/h}$, but cannot recall which speed corresponds to which section. We can ensure that the total time in hours spent by the driver to cover the three sections was:

(a) less than or equal to 13 hours;
(b) more than or equal to 13 hours and less than or equal to 16 hours;
(c) more than or equal to 16 hours and less than or equal to 17 hours;
(d) more than or equal to 15 hours and less than or equal to 18 hours;
(e) more than or equal to 18 hours.
