Question

Convert: There are 1,000 meters in a kilometer, and 3,600 seconds in an hour. You can convert units of meters per second (m/s) into kilometers per hour (km/h) by multiplying by 3,600 and dividing by 1,000. (Hint: That is the same thing as multiplying by 3.6.)
A. What is the speed of a cheetah in kilometers per hour?



B. What is the speed of a person in kilometers per hour? ​

Answer 1

The required speed in km/hr are 108km/hr and 25.704km/hr

How to calculate the distance and speed of an object

Given the following conversion rate

• 1 km = 1000m
• 1 hr = 3600seconds

Given that the speed of cheetah is 30meters per second. Converting to m/s will give:

30m/s = $\frac{30m}{1s} \times \frac{1km}{1000m} \times \frac{3600s}{1hr}$

30m/s = 30 * 3.6

30m/s = 108km/hr

For the person with speed of 7.14m/s, the value in km/hr is expresssed as:

7.14m/s = 7.14 * 3.6

7.14m/s = 25.704km/hr

Hence the required speed in km/hr are 108km/hr and 25.704km/hr
