Joe rides on his bicycle in a straight line with an average speed of 12.5 km/h. How fast is he
traveling in m/s? (Ans: 3.47 m/s)
To find out how fast Joe is traveling in m/s, we need to convert his average speed from km/h to m/s.
First, let's convert his speed from km/h to m/s.
1 km = 1000 m
1 hour = 3600 seconds
So, to convert km/h to m/s, we need to divide the speed value by 3.6 (since 1 km/h = 1000 m / 3600 s = 1/3.6 m/s).
Let's apply this conversion to Joe's speed of 12.5 km/h:
12.5 km/h ÷ 3.6 = 3.47 m/s
Therefore, Joe is traveling at a speed of 3.47 m/s.
