Nora drove to California over three days. The first day she drove 406.5 kilometers, 492.67 kilometers the second day, and 187.75 kilometers the third day. Select the strip diagram that represents the number of kilometers Nora drove to reach California.

• 406.50 + 492.67 + 187.75 = 575.82

• 492.67 + 187.75 - 406.5 = 273.92
