Sravan travelled for 15 hours. He covered the first half of the distance at 45 kmph and remaining half of the distance at 30 kmph. Find the distance travelled by Sravan? Choose the correct choice from the following options:	A) 520	B) 540	C) 550	D) 560	E) 440
Let the distance travelled be x km.   Total time = (x/2)/45 + (x/2)/30 = 15 =&gt; x/90+ x/60 = 15 =&gt; (2x + 3x)/180 = 15   =&gt; x = 540 km   Answer:540
