Respuesta :
=9 * 1000 / 3600
=9000 / 3600
=2.5m/s
note that 1000m makes 1km and 3600seconds make an hour
=9000 / 3600
=2.5m/s
note that 1000m makes 1km and 3600seconds make an hour
Answer: Option (a) is the correct answer.
Explanation:
We have to convert 9 Km/hr into m/s.
It is known that 1 Km = 1000 meters.
Also, it is known that 1 minute = 60 seconds
Therefore, total number of seconds in 60 minutes = 60 × 60 seconds = 3600 seconds
Thus, there are 3600 seconds in one hour.
So, 9 Km/hr = [tex]\frac{9 \times 1000 meters}{3600 seconds}[/tex]
= 2.5 m/s
Hence, we can conclude that Matty's speed in m/s is 2.5 m/s.
