A Bus travels first half distance between two places with a speed of 40 kmph and the rest half distance with a speed of 60 kmph. The average speed of the Bus is ?  Choose the correct choice from the following choices:	A) 48 kmph	B) 78 kmph	C) 28 kmph	D) 18 kmph	E) 98 kmph
Explanation:   we know that speed = distance traveled/time taken   let the total distance traveled by the car is 2x km.   then time taken by it to cover first half is hour.   and for second half is hour.   Then average speed= total distance travelled / total time taken.   i.e.   =&gt;   = 48 kmph.   48 kmphnswer: 48 kmph
