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 from the following:
A) 520
B) 620
C) 820
D) 740
E) 720
Distance = (240 x 5) = 1200 km.   Speed = Distance/Time   Speed = 1200/(5/3) km/hr. [We can write 1 2/3 hours as 5/3 hours]   Required speed = (1200 x	3/5) km/hr = 720 km/hr   Answer 720) 720 Km/hr
<result>E</result>
