Respuesta :
1 km = 1000 m
1 h = 3600 s
75 km/h
75 *1000 m / 3600 s
75 * 5 m / 18 s
25 * 5 m / 6 s
125 m / 6 s
20.8 m/s
answer is c.
1 h = 3600 s
75 km/h
75 *1000 m / 3600 s
75 * 5 m / 18 s
25 * 5 m / 6 s
125 m / 6 s
20.8 m/s
answer is c.
For this case we must apply the following conversion factors:
[tex]1km = 1000m\\1h = 3600s[/tex]
We then have the following speed:
[tex]75 \frac {km} {h}[/tex]
Applying the conversion factors we have:
[tex]75 \frac {km} {h} 1000 \frac {m} {km} \frac {1} {3600} \frac {h} {s}[/tex]
Rewriting we have:
[tex]20.8 \frac {m} {s}[/tex]
Answer:
The speed of the car in m / s is:
[tex]20.8 \frac {m} {s}[/tex]
