Answer 1

i hate word problems
don't you?

Answer 2

Yass!

Answer 3

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

Answer 4

we can solve \[4R=4.5(R-5)\] for R

Answer 5

wait 1 sec...

Answer 6

R = 45
rite?

Answer 7

yeah! but we are not done

Answer 8

mk

Answer 9

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