The distance between the nest and the ditch is 100 meters.   15 times mean = A crow leaves its nest, and flies back ( going and coming back) i.e. 2 times we get total 30 rounds.   So the distance is  30 * 100= 
<gadget id="calculator"> 30 * 100</gadget>
<output>3_000</output>
3000.   5= ST   3000/1.5 = T , I think we can take 3000 meters as 3 km, then only we get T = 2.( 1000 meters = 1 km)   5)
<result>D</result>
