Answer:
72 kilometers per hour = 20 meters per second
Explanation:
Speed of tuna, v = 72 km/hr
We need to find Tuna's speed in meters per second. To convert km/hr to m/s we must use the following conversions as :
[tex]1\ km=1000\ m[/tex]
And, [tex]1\ h=3600\ s[/tex]
[tex]72\ km=72000\ m[/tex]
[tex]Speed=\dfrac{72\ km}{1\ h}=\dfrac{72000\ m}{3600\ s}[/tex]
Speed = 20 m/s
So, Tuna's is travelling with a speed of 20 meters per second. Hence, this is the required solution.
