The height of the car at the end of the ride is 4 meters

Initial position of roller coaster= 1 meter above the ground=+1

Now, Position of the Roller coaster when it goes downwards by 4 meters

                                                                      =1-4

                                                                      = -3 meter

Now, it rises 13 meter above from it's final position.

So, Position of Roller coaster = -3 +13=10 meter above from ground level=+10

Now, The Roller coaster drops down by 6 meters from the last position it was,

 So, Position of Roller Coaster

   =10+(-6)

    =4 meters above the ground level  

Height of car from ground level=4 meter
