A bus covers a certain distance at aspeed of 240 kmph in 5hours. To cover the same distance in 1hr, it must travel at a speed of?	Choose the correct choice from the following.
A) 550 km/hr  B) 590 km/hr  C) 600 km/hr  D) 610 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
