Question

Matty jogs 9 km/hr. Compute Matty's speed in m/s.

a. 2.5 m/s
b. 15.0 m/s
c. 25.0 m/s
d. 150.0 m/s

Answer 1

=9 * 1000 / 3600
=9000 / 3600
=2.5m/s
note that 1000m makes 1km and 3600seconds make an hour

Answer 2

Answer: Option (a) is the correct answer.

Step-by-step 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 =
`(9 * 1000 meters)/(3600 seconds)`

= 2.5 m/s

Hence, we can conclude that Matty's speed in m/s is 2.5 m/s.
