An bus covers a certain distance at a speed of 220 kmph in 5 hours. To cover the samedistance in 1hr, it must travel at a speed of? Choose the correct choice from the following options:
A) 600 km/hr B) 660 km/hr C) 730 km/hr D) 750 km/hr E) 760 km/hr
Distance = (220 x 5) = 1100 km.   Speed = Distance/Time   Speed = 1100/(5/3) km/hr. [We can write 1 hours as 5/3 hours]   Required speed = 1100 x 3 km/hr = 660 km/hr.   660 km/hr
