Hey there!
Here is your answer:
<u>The proper answer to this question is "40".</u>
Reason:
<u>40/x=100/45</u>
<u>(40/x)*x=(100/45)*x - we multiply both sides of the equation by x</u>
<u>40=2.22222222222*x - we divide both sides of the equation by (2.22222222222) to get x</u>
<u>40/2.22222222222=x </u>
<u>18=x </u>
<u>x=18</u>
<span>45% of 40=18

Distance =2438.9 miles
Time=18 hours 20 minutes.
First we convert the time to hour
60 minutes = 1 hour

rate=distance/time
=2438.9/18.33
=133.06 miles per hour
Her average speed is 133.06 miles per hour
