Solved Example on Kilometer Per Hour
Sam drove his car at the rate of 60,000 meters per hour. Find his speed in kilometers per hour.
Choices:
A. 6000 km/hr
B. 60 km/hr
C. 600 km/hr
D. 6 km/hr
Correct Answer: B
Solution:
Step 1: 1000 meters = 1 kilometer
Step 2: So, 60,000 meters = 60 kilometers [60,000/1000 = 60]
Step 3: Therefore, his speed is 60 km/h
Quick Summary
- km/h is a unit for measuring speed and velocity.
- 1 km/h is approximately equal to 0.62 miles per hour.
- km/h is commonly used in speedometers.
