C. 4000 meters per hour
D. 40,000 meters per hour



Answer :

To convert kilometers per hour to meters per hour, you need to know that there are 1,000 meters in a kilometer.

Here’s the step-by-step process:

1. Start with the given speed in kilometers per hour, which is 40 kilometers per hour.
2. Understand that 1 kilometer equals 1,000 meters.
3. Multiply the number of kilometers by the number of meters in each kilometer to convert the speed to meters per hour.

So:
[tex]\[ 40 \text{ kilometers} = 40 \times 1,000 \text{ meters} \][/tex]

[tex]\[ 40 \times 1,000 = 40,000 \text{ meters per hour} \][/tex]

Therefore, 40 kilometers per hour is equivalent to 40,000 meters per hour.

The correct answer is:
D) 40,000 meters per hour
