For this case we must apply the following conversion factors:
\(1km = 1000m\\1h = 3600s\)
We then have the following speed:
\(75 \frac {km} {h}\)
Applying the conversion factors we have:
\(75 \frac {km} {h} 1000 \frac {m} {km} \frac {1} {3600} \frac {h} {s}\)
Rewriting we have:
\(20.8 \frac {m} {s}\)
Answer:
The speed of the car in m / s is:
\(20.8 \frac {m} {s}\)
