Sarah and nancy each drive 600 miles. sarah's average speed is represented by x miles per hour. what does the denominator of the rational expression 600x−4600x-4 mean in the context of this situation?

entering that problem on the tube might get you an answer

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m

hope this !

let me know
