The correct answer is 1.4285714.
In physics, velocity is characterised as a vector measurement of the motion's direction and speed. To be more precise, the rate of change in an object's position relative to a frame of reference and time is another way to describe velocity. The definition of velocity simply states the rate of motion of an object in a specific direction. It determines how quickly or slowly something is going.
Velocity = distance/ time
Thus time = distance/velocity
Here velocity = 350m/s
diatnce = 500 m
time = 500/350
time = 1.42857142857
t= 200m /350m/s = 1.4285714

Explanation:
The Green work gymno means Naked
This depends on the original mass of the object having its mass doubled and the the original distance before the distance was tripled.
