Question: A car travels 60 km in 1 hour. What is its speed in m/s?

Options:

Correct Answer: 16.67 m/s

Solution:

Speed = Distance/Time = 60 km/h = (60 * 1000 m)/(3600 s) = 16.67 m/s.

A car travels 60 km in 1 hour. What is its speed in m/s?

A car travels 60 km in 1 hour. What is its speed in m/s?

Step 1: Understand that speed is calculated by dividing distance by time.
Step 2: Identify the distance traveled by the car, which is 60 kilometers.
Step 3: Identify the time taken for the journey, which is 1 hour.
Step 4: Convert the distance from kilometers to meters. Since 1 kilometer is equal to 1000 meters, multiply 60 by 1000 to get 60000 meters.
Step 5: Convert the time from hours to seconds. Since 1 hour is equal to 3600 seconds, multiply 1 by 3600 to get 3600 seconds.
Step 6: Now, use the formula for speed: Speed = Distance / Time. Substitute the values: Speed = 60000 meters / 3600 seconds.
Step 7: Calculate the speed. 60000 divided by 3600 equals approximately 16.67 meters per second.

Speed Calculation – Understanding how to calculate speed using the formula Speed = Distance/Time and converting units from kilometers per hour to meters per second.
Unit Conversion – The process of converting kilometers to meters and hours to seconds to ensure consistent units in the speed calculation.
