Answer
The coefficient for $x_1$: if the percent of the time the shooter’s aim was on target increases by 1 and the distance the barrel of the pistol moves horizontally while aiming remains constant, then the score that an individual will receive on the shot, will increase by 0.02, on average.
The coefficient for $x_2$: if the distance the barrel of the pistol moves horizontally while aiming increases by 1 mm and the percent of the time the shooter’s aim was on target remains constant, then the score that an individual will receive on the shot, will decrease by 0.03, on average.
