Question

If a rocket travels 5600km in 3 hours, what is its speed (m/min)?

Answer 1

31111.11 m/min

Explanation:

We can calculate the speed, by means of the quotient between the distance and the time. But since it must be expressed in meters per minute, we must convert in each case. Taking into account that 1 kilometer is 1000 meters and 1 hour is 60 minutes, therefore:

`\begin{gathered} 5600km\cdot(1000)/(1km)=5600000\text{ m} \\ 3\text{ h}\cdot\frac{60\text{ min}}{1\text{ h}}=180\text{ min} \\ \text{Therefore, the speed is:} \\ v=(5600000)/(180) \\ v=31111.11\text{ m/min} \end{gathered}`

Therefore, the speed is 31111.11 meters per minute
