A particle is moving with a uniform acceleration along a straight line. Its velocities at A and B are respectively 7m/s^2 and 17m/s^2. M is the mid point of A and B. If t1is the time tajen to go from A to M and t2 is the time taken to go from M to B. Then what would be the ratio of t1/t2?

the qustion is not proper. Is it a acceleration or velocity? . if velocity then it must be in m/s 
repost correctly !!

dear student or sir 
a small mistake occured in your typing. velocity is considered in m/s and acceleration is considered in m/s^2. so I solve velocity in this question
given conditions in the question are
  1. particle is having uniform velocity.
  2. velocity at A is 7m/s
  3. velocity at B is 17m/s
  4. M is midpoint of AB. so let us consider the distance between AB is “d”
  5. therefore distance between AM is d/2 and distance between MB is d/2
  6. here t1 is the time taken to reach A to M. 
  7. so velocity=displscement /time
  8. time= displacement / velocity
  9. for case AM
  10. t1 =d/2*7  (*means multiplication)
  11. similarily t2=d/2*17
  12. t1/t2= 17/7 (on solving)
therefore the solution is t1/t2= 17/7
