An bus covers a certain distance at a speed of 240 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) 700 km/hr B) 720 km/hr C) 870 km/hr D) 869 km/hr E) 890 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.   720 km/hr
