Question

A tuna travels at a speed of 72 Kilometers per hour. What is the speed of tuna in meters per second?

Answer 1

That would be 72,000 meters

Answer 2

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 :

$1\ km=1000\ m$

And, $1\ h=3600\ s$

$72\ km=72000\ m$

$Speed=\dfrac{72\ km}{1\ h}=\dfrac{72000\ m}{3600\ s}$

Speed = 20 m/s

So, Tuna's is travelling with a speed of 20 meters per second. Hence, this is the required solution.
