An bus covers a certain distance at a speed of 250 kmph in 5 hours. To cover the samedistance in 1hr, it must travel at a speed of?	Select the correct option:
A) 600 km/hr
B) 720 km/hr
C) 730 km/hr
D) 750 km/hr
E) 760 km/hr
Distance = (250 x 5) = 1250 km.   Speed = Distance/Time   Speed = 1250/(5/3) km/hr. [We can write 1 hours as 5/3 hours]   Required speed = 1250 x 3 km/hr = 750 km/hr.   750 km/hr
