Solve the problem.A projectile is fired from a height of 5.8 feet with an initial velocity of 187 ft/sec at an angle of 30° with the horizontal. The parametric equations for the path of the projectile are x = (187 cos 30°)t, and y = 5.8 + (187 sin 30°)t - 16t2,where x and y are in feet and t is in seconds. Find the total horizontal distance traveled by the projectile. Round your answer to the nearest tenth of a foot.
