## sissyedgar one year ago Two cars traveled equal distances in different amounts of time. Car A traveled the distance in 4 h, and Car B traveled the distance in 4.5 h. Car B traveled 5 mph slower than Car A. How fast did Car B travel? mph

i hate word problems don't you?

Yass!

distance is rate times time, so $D=4\times R=4.5\times( R-5)$

4. anonymous

we can solve $4R=4.5(R-5)$ for R

5. sissyedgar

wait 1 sec...

6. sissyedgar

R = 45 rite?

7. anonymous

yeah! but we are not done

i had $$R$$ as the rate of the faster car, so the rate of the slower car is $$45-5=40$$

right! Ty Satellite!
