Pavan travelled for 11 hours. He covered the first half of the distance at 30 kmph and remaining half of the distance at 25 kmph. Find the distance travelled by Pavan.  Select the correct option:
A) 208 km	B) 637 km	C) 342 km	D) 300 km	E) 543 km
Let the distance travelled be x km.   Total time = (x/2)/30 + (x/2)/25 = 11   =&gt; x/60 + x/50 = 11 =&gt; (5x + 6x)/300   = 11 =&gt; x = 300 km   Answer:300 km
