Using the kinematic equations, find the horizontal range (aka x-displacement) and the time it took for an object launched from a height of 5m with an initial velocity of 15m/s and at an angle of 20 to reach the ground. The object follows projectile motion. Ignore air resistance. Show all work.

The answer given for the horizontal range is 23.4m and the time is 1.66s. However, when I try to calculate the time, I keep getting 0.52s. I used the kinematic equation v=vi+at to solve for t.
