Question

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

Answer 1

Matty's speed of 9 km/hr is equivalent to 2.5 m/s when converted using the relationship where 1 km equals 1000 meters and 1 hour equals 3600 seconds.

Step-by-step explanation:

To compute Matty's speed in meters per second (m/s), we need to convert from kilometers per hour (km/h) to m/s. To do this, we can use the conversion rate where 1 km equals 1000 meters, and 1 hour equals 3600 seconds.

First, we convert Matty's speed to meters:
9 km/h = 9 × 1000 m/h = 9000 m/h.

Then, we convert hours to seconds:
9000 m/h × (1 h / 3600 s) = 9000 m / 3600 s = 2.5 m/s.

Therefore, Matty's speed in meters per second is 2.5 m/s.

Answer 2

Step-by-step explanation:

1km = 9000 m

1 min = 60 sec

So 60 min = 3600 sec

In this way Matty jogs 9000m /3600sec
