Answer:

1 km / 1000 m

60 min / 1 hr

60 s / 1 min

Explanation:

To convert 75 m/s to km/h, we need to convert m to km and s to hr.

To convert m to km, we use the following conversion factor

1 km/ 1000 m

And to convert s to hr, we use the factors

60s / 1 min x 60 min/ 1h

Then, we can convert 75 m/s to km/h as follows

[tex]75\text{ m/s}\times\frac{1\text{ km}}{1000\text{ m}}\times\frac{60\text{ s}}{1\text{ min}}\times\frac{60\text{ min}}{1\text{ h}}=270\text{ km/h}[/tex]

Therefore, the answers are

1 km / 1000 m

60 min / 1 hr

60 s / 1 min
