Question

Kyzell is traveling 15 meters per second. Which expression could be used to convert this speed to kilometers per hour.

Answer 1

Given:

Kyzell is traveling 15 meters per second

we need to convert meters per second to kilometers per hours

As we know:

1 km = 1000 meters

So, 1 meters = 1/1000 kilometers

And, 1 Hour = 60 minutes = 3600 seconds

So, 1 seconds = 1/3600 Hours

So,

`15(meters)/(\sec onds)=15\cdot(1)/(1000)\cdot3600\cdot\frac{kilometes}{\text{hours}}=54(kilometrers)/(hours)`

So, the answer will be:

15 meters per second = 54 kilometers per hour
