A tennis player serves the ball at a speed of 180 km/h. What is the speed in meters per second? (2022)

Step 1: Understand that we need to convert kilometers per hour (km/h) to meters per second (m/s).
Step 2: Know that 1 kilometer is equal to 1000 meters.
Step 3: Know that 1 hour is equal to 3600 seconds.
Step 4: Start with the speed of the tennis player, which is 180 km/h.
Step 5: Multiply 180 km/h by the conversion factor for kilometers to meters: 180 km/h × (1000 m / 1 km).
Step 6: This gives us 180,000 m/h (since 180 × 1000 = 180,000).
Step 7: Now, we need to convert hours to seconds. Divide by the number of seconds in an hour: 180,000 m/h ÷ 3600 s/h.
Step 8: Calculate 180,000 ÷ 3600, which equals 50 m/s.
Step 9: Therefore, the speed of the tennis player in meters per second is 50 m/s.

Unit Conversion – The process of converting speed from kilometers per hour to meters per second using the appropriate conversion factors.
