An bus covers a certain distance at a speed of 240 kmph in 5 hours. To cover the samedistance in 1hr, it must travel at a speed of?  Choose the most appropriate option:
A) 520 km/hr  B) 640 km/hr  C) 656 km/hr  D) 731 km/hr  E) 720 km/hr
Distance = (240 x 5) = 1200 km.   Speed = Distance/Time   Speed = 1200/(5/3) km/hr. [We can write 1 hours as 5/3 hours]   Required speed = 1200 x	3	km/hr	= 720 km/hr.   5   720 km/hr
