Cem attached a rope to one end of his skateboard's steering rod, with the hanging part having a length of 46 cm. When the skateboard's adjustable connecting rod has a length of 60 cm as shown in Figure 1, the distance from the closest point of the rope to the ground to the point where the connecting rod joins the skateboard is 50 cm. When Cem increased the length of the skateboard's connecting rod as shown in Figure 2, the distance from the closest point of the rope to the ground to the point where the connecting rod joins the skateboard became 80 cm. Accordingly, how many cm longer is the connecting rod in Figure 2 compared to the connecting rod in Figure 1? A) 30 B) 40 C) 50 D) 60 E) 70
