The car travels 172.0m horizontally and 16.6m vertically
The car travels 172.8m in 12s, given by the equation d = ½at² = ½ * 2.4m/s² * (12s)²
The horizontal distance is given by x = d * cos(θ) = 172.8m * cos(5.5°) = 172.0m
The vertical distance is given by y = d * sin(θ) = 172.8m * sin(5.5°) = 16.6m
NOTE: when calculating cos() and sin(), make sure your calculator is in degree mode
