Question

what is the displacement of the car from the star to the flags? -10 -8 -6 -4 -2 0 2 4 6 8 10 km 6 km 2 km 12 km 8 km

Explanation:

Step1: Identify positions

The star is at -8 km (from the number line: the star is above -8), and the flags are at 0 km? Wait, no, wait. Wait, the car is at the star? Wait, the star is at -8? Wait, the number line: let's check the grid. Wait, the car is at the star, which is at -8? Wait, no, the green arrow is from star to flags. Wait, the flags are at 0? Wait, no, let's look at the number line. The star is at -8 (since the car is at -8, with the star above it), and the flags are at 0? Wait, no, the purple arrow is at the flags, which are at 0? Wait, no, the number line has marks at -10, -8, -6, -4, -2, 0, 2, 4, 6, 8, 10. The star is at -8 (the car is at -8, star above), and the flags are at 0? Wait, no, the green arrow is from star to flags. Wait, the distance between -8 and 0? No, wait, maybe the star is at -8, and the flags are at 0? Wait, no, let's count the units. From -8 to 0: that's 8 units? Wait, no, the options include 8 km. Wait, let's check again. The star is at -8 (position -8 km), and the flags are at 0? Wait, no, the flags are at 0? Wait, the number line: the flags are at 0 (the two flags are at 0, since the purple arrow is at 0). So displacement is final position minus initial position. Initial position (star) is -8 km, final position (flags) is 0 km? Wait, no, that would be 0 - (-8) = 8 km. Yes, that matches the option 8 km.

Step2: Calculate displacement

Displacement = final position - initial position. Initial position (star) is -8 km, final position (flags) is 0 km? Wait, no, wait the star is at -8, and the flags are at 0? Wait, no, maybe the star is at -8, and the flags are at 0? Wait, the number line: the star is at -8 (the car is at -8, star above), and the flags are at 0 (the two flags are at 0). So displacement is 0 - (-8) = 8 km. So the correct answer is 8 km.

Answer:

8 km (the option with "8 km")
