Bond (007) wants to move from a point A to point D, but here 2 watchtowers (B & C ) are present in the way of A to D. soldier on watchtowers has rifles with range of 1 kilometer. A,B,C,D are in straight line and distance between All points is 1 kilometer respectively. Find the minimum distance covered by 007 in journey between point A to D while his distance from watchtowers is always >=1 .

• ans is 1+pie (3.14) because range of watchtower creats circulare range so from point A to B distance = (2 * pie * radius )/ 4 = 2*pie/4
  for point B to C minimum distance is 1 km (2*pie/4)+1+(2*pie/4)= 1+Pie(3.14)

• 1+pie(3.14)
• 10 years agoHelpfull: Yes(9) No(1)
• its pie+1.
  
  2(pie)1/4---a->b
  +
  1 b->c
  +
  2(pie)1/4- --c->d
  =pie+1
  
  Draw a diagram to understand.
  distance covered from a->b and c->d using quarter of circumference of circle.

• pls any one explaine me clearly....why we have to consider it as circle??????????
  
• 9 years agoHelpfull: Yes(4) No(0)
• because here we take 1/4 th part of circle's circumference , draw a diagram ,u can understand easily
  
• 10 years agoHelpfull: Yes(2) No(3)
• I THINK IT S 3Km OR 3000M
  
• 9 years agoHelpfull: Yes(2) No(2)
• ans is 4.14 km
• 9 years agoHelpfull: Yes(2) No(1)
• Anuj please can you tell me why is 2pie is divided by 4
  
• 10 years agoHelpfull: Yes(1) No(0)
• i think the answer it 3 km
• 9 years agoHelpfull: Yes(1) No(2)
• the answer will be 3km because the distance between bond and tower is always greater than and equal to one. so bond will be out of range of he snipers as gun range is 1km. he can follow a straight path of (1+1+1 km). point to note that the snipers are not in ground.

• 1 + pie/3 will be the minimum distance travelled by bond
• 9 years agoHelpfull: Yes(1) No(0)
• bond has to travel on quarter circumference of circle centered B then wakl streight 1 km then again walk on circumference of circle centered C.
  = 2*pi*1/4 + 2*pi*1/4 + 1
  = 1.57 +1.57 + 1 =4.14
• 9 years agoHelpfull: Yes(1) No(0)
• i think its ans will be 4km....
  
• 10 years agoHelpfull: Yes(0) No(4)
• ans is (pie)/2
  
• 9 years agoHelpfull: Yes(0) No(1)
• anyone plz expalin the solution properly, my doubt is, A B C D are in a straightline then, how they are separated by 1km distance each??
• 9 years agoHelpfull: Yes(0) No(1)
• 1+pie/2=2.57
  
• 9 years agoHelpfull: Yes(0) No(0)
• The bond will travel through a circular path making a semicircle of 1.5 radius........
  circumferene of semiircle is pi*r
  ans is 4.71
• 9 years agoHelpfull: Yes(0) No(0)
• a......................b.......................c.............................d
  
  so 007 has to follow a circular track of 3km radius...
