Question

A cheetah was observed running at a speed of 30.6 m/s. Use the following facts to convert this speed to kilometers per hour (km/h). 1 km = 1000 m 1 min = 60 sec 1 hour = 60 min Round your answer to the nearest tenth. Hint: It is best to wait to round until you have completed all the calculations.

Answer 1

110.16km/hr.

Step-by-step explanation:

The speed of the cheetah in m/s = 30.6

Now:

Next:

`\begin{gathered} 1\text{ hour = 60 minutes = 60 x 60 seconds} \\ 1\text{ hour = 3600 seconds} \\ \text{Therefore:} \\ 1\text{ second=}(1)/(3600)\text{ hour} \end{gathered}`

Therefore, 30.6 m/s in km/hr will be:

The speed of the cheetah in km/hr is 110.16km/hr.
