An aeroplane covers a certain distance at a speed of 300 kmph in 6 hours. To cover the same distance in 1 2/3 hours, it must travel at a speed of: Choose the correct answer.
A) 1008 kmph
B) 760 kmph
C) 1080 kmph
D) 1070 kmph
E) none
Explanation: Distance = (300 x 6) = 1800 km.   Speed = Distance/Time   Speed = 1800/(5/3) km/hr. [We can write 1 2/3 hours as 5/3 hours]   Required speed = 1800 x 3/5 km/hr = 1080 km/hr.   Answer: Option 1080 kmph
