A car is traveling at a rate of 30meters per second. What is the car's rate in kilometers per hour? How many kilometers will the car travel in 4 hours? Do not round your answers.
OpenStudy (anonymous):
14.4 KM
OpenStudy (anonymous):
is that the distance traveled in 4 hours?
OpenStudy (anonymous):
Yes, do you have a answer choice?
OpenStudy (mathmale):
We need conversion factors!
\[(\frac{ 30 m }{ 1 \sec })(\frac{ 3600 \sec }{ 1 hr })(\frac{ 1 km }{ 1000 m })\]

No i don't. I have to fill it in. I also need the rate in kilometers per hour though
OpenStudy (mathmale):
Multiply that by (4 hr) to obtain the distance traveled in that period of time.
OpenStudy (anonymous):
3.6 KM per hour
OpenStudy (mathmale):
DD: Please multiply that conversion of 30 m/ hr through to obtain the correct speed in km/hr.

hmm it's saying that is incorrect @DragonFlame
