An aeroplane covers a certain distance at a speed of 120 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 answers.
A) 520	B) 620	C) 820	D) 740	E) 720
Distance = (120 x 5) = 600 km.   Speed = Distance/Time   Speed = 600/(5/3) km/hr. [We can write 1 2/3 hours as 5/3 hours]   Required speed = (600 x 3/5) km/hr = 360 km/hr   520nswer 520) 360 Km/hr
