Answer:
 Bolt will travel a distance of 3750 meter horizontally from the point where it left the plane until it lands on the ground.
Step-by-step explanation:
 We have equation of motion , 
 , s is the displacement, u is the initial velocity, a is the acceleration and t is the time.
, s is the displacement, u is the initial velocity, a is the acceleration and t is the time.
 Here bolt has horizontal and vertical motion, but the horizontal velocity remains same because there is no acceleration acting in the horizontal direction.
 In this case initial velocity = 150 m/s, time taken to reach ground = 25 seconds and acceleration is zero.
 Substituting 
 

 So bolt will travel a distance of 3750 meter horizontally from the point where it left the plane until it lands on the ground.
