To arrange the planets by their orbital speeds from slowest to fastest, we need to consider their orbital periods and distances from the Sun. Orbital speed increases as you get closer to the Sun.
The correct order from slowest to fastest orbital speed is:
- Jupiter (slowest)
- Saturn
- Earth
- Mercury (fastest)
Based on the options provided, the correct arrangement is:
Jupiter < Saturn < Earth < Mercury.
However, since this exact combination is not present in your options, the closest correct arrangement that fits the trend is:
Saturn < Jupiter < Mars < Mercury.
But it should be noted that Mars is actually faster than both Saturn and Jupiter, so this option is not correct.
The proper order of speeds, from slowest to fastest, is not perfectly reflected in your given choices. If none of the options fit accurately, it suggests that the available choices might be incorrect.
Given the criteria, from the choices available, none correctly reflect the proper arrangement.
