Two people A and B starts running at 10:00 AM towards north at a speed of 40Kmph and 60Kmph respectively. After 2 hours(12:00 noon ), A turned left and B turned right. They stopped at 2:00 PM.Find the distance between A and B at 2:00 PM.

• if asked displacement sqrt(200^2+40^2)=204
  if asked distance 80+40+120=240
  i think so....

• there is no need to apply formula its a general common sense problem ans : 200 i.e (120+80)=200

• plz explain it properly

• correct ans is 203km... distance between A & B is asked so we wl take displacement..

• the answer will be the distance between (-80,0) and (120,40) and by distance formula sqrt((x2-x1)2-(y2-y1)2)=144

• 240...A has covered 80 km in left direction & B has covered 120 km in right direction ...and in north their difference is 40 so 80+120+40

• ans will be..160
  donot run after the formula..
  draw the dia accordingly ...u'll get the answer

• ans is 240 =>120+80+(40)=240
• 11 years agoHelpfull: Yes(2) No(4)
• ans is 240..bcs 120+40+80..the ans will be 240 only
• 11 years agoHelpfull: Yes(2) No(4)
• if the starting point is (0,0) then
  at 2:00 pm
  A will be at (-80,80)
  B will be at (120,120)
  so distance between them will be
  sqrt((-80-120)^2+(80-120)^2)
  equals to 40(sqrt26).

• ans is 400km... distance...
  at 2:00pm a,b will be, 160km,120km away from turning point....

• what is displacement there? what is the formula for it?
