Answer:

  yes

Step-by-step explanation:

We can use the fact that the rate is a constant to find the time t it would take Billie to bike 24 miles.

  time/distance = (3/4 h)/(9 mi) = t/(24 mi)

Multiplying by 24 mi, we have ...

  t = (3/4 h)(24/9) = 2 h

At the same rate, Billie can bike 24 miles in 2 hours.
