ok

Answer 5

donused

Answer 6

4.5 hr x what?

Answer 7

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?

distance_A = (rate_A) * 4 hours
distance_B = (rate_B) * 4.5 hours

rate_B = rate_A - 5
distance_A = distance_B

Answer 8

yes!

Answer 9

is it 55mph?

Answer 10

distance_A = (rate_A) * 4 hours
distance_B = (rate_B) * 4.5 hours
rate_B = rate_A - 5
distance_A = distance_B

call rate_A = x

x*4 = (x-5)*4.5

4x = 4.5x - 5*4.5

4x = 4.5x - 22.5

.5x = 22.5

x = 22.5 / .5 = 45
