Bonjours !

J'aurais besoin de réponse et t'explication éventuellement :)

Answer:

1) 15 feet per second

2) distance after 3 seconds 45 feet

3) slower

Step-by-step explanation:

1) 30/2 = 15

2) 15 x 3

3) 55/4 = 13.75 < 15

Final answer:

The scooter travels 15 feet after 1 second, 45 feet after 3 seconds, 60 feet after 4 seconds, and 75 feet after 5 seconds. The speed of the scooter is 15 feet per second. The skateboard is going slower than the scooter.

Explanation:

To complete the double number line, we need to determine the distance the scooter travels after 1, 3, 4, and 5 seconds. Since the scooter travels 30 feet in 2 seconds at a constant speed, we can determine the distance for each time by finding the proportion:

After 1 second: 30 feet / 2 seconds = 15 feet

After 3 seconds: 30 feet / 2 seconds * 3 seconds = 45 feet

After 4 seconds: 30 feet / 2 seconds * 4 seconds = 60 feet

After 5 seconds: 30 feet / 2 seconds * 5 seconds = 75 feet

The speed of the scooter is the same as its constant speed, which is 30 feet / 2 seconds = 15 feet per second.

The distance the scooter travels after 3 seconds is 45 feet.

Since the scooter traveled 30 feet in 2 seconds, and the skateboard traveled 55 feet in 4 seconds, we can compare their speeds. The scooter traveled 30 feet in 2 seconds, which means its speed is 30 feet / 2 seconds = 15 feet per second. The skateboard traveled 55 feet in 4 seconds, so its speed is 55 feet / 4 seconds = 13.75 feet per second. Therefore, the skateboard is going slower than the scooter.

Final answer:

When converted to meters, 0.100 kilometers, 10,000 centimeters, and 100,000 millimeters all equal 100 meters. However, 10 hectometers equals 1000 meters, hence it does not equate to 100 meters.

Explanation:

The units you provided for comparison are 0.100 kilometers, 10 hectometers, 10,000 centimeters, and 100,000 millimeters. Let's convert them all to meters using the following metric conversions:

• 1 kilometer = 1,000 meters
• 1 hectometer = 100 meters
• 1 centimeter = 0.01 meters
• 1 millimeter = 0.001 meters

So, based on the metric conversions:

• 0.100 kilometers = 100 meters
• 10 hectometers = 1000 meters
• 10,000 centimeters = 100 meters
• 100,000 millimeters = 100 meters

As such, 10 hectometers does not equal 100 meters. Instead, it amounts to 1000 meters.
