An aeroplane covers a certain distance at a speed of 240 kmph in 5 hours. To cover the same distance in 1 2/3 hours, it must travel at a speed of:  Choose the correct choice:	A) 300 kmph	B) 360 kmph	C) 600 kmph	D) 720 kmph	E) 650 kmph
Distance = (240 x 5) = 1200 km.   Speed = Distance/Time   Speed = 1200/(5/3) km/hr. [We can write 1 2/3hours as 5/3 hours]   Required speed = (1200 x3/5)	km/hr	= 720 km/hr.   Answer :720 kmph
