Question: If a car travels 100 kilometers in 2 hours, what is its speed in meters per second?

Options:

Correct Answer: 20 m/s

Solution:

Speed = distance/time = (100000 m)/(7200 s) = 27.78 m/s, approximately 20 m/s.

If a car travels 100 kilometers in 2 hours, what is its speed in meters per second?

If a car travels 100 kilometers in 2 hours, what is its speed in meters per second?

Step 1: Understand that speed is calculated by dividing distance by time.
Step 2: Convert the distance from kilometers to meters. Since 1 kilometer is equal to 1000 meters, 100 kilometers is equal to 100,000 meters.
Step 3: Convert the time from hours to seconds. Since 1 hour is equal to 3600 seconds, 2 hours is equal to 7200 seconds.
Step 4: Use the speed formula: Speed = distance / time. Plug in the values: Speed = 100000 meters / 7200 seconds.
Step 5: Calculate the speed. 100000 divided by 7200 equals approximately 13.89 meters per second.
Step 6: Round the answer to a reasonable approximation, which is about 14 m/s.

Speed Calculation – Understanding how to calculate speed using the formula speed = distance/time.
Unit Conversion – Converting kilometers to meters and hours to seconds to ensure consistent units.
