Answer:
running 1.5 hours
Walking 4.5 hours
Step-by-step explanation:
Let the amount of time she spends on walking be x
d/3 + d/9 = 6 Multiply by 9
3d + d = 6*9
4d = 54 Divide by 4
4d/4 = 54/4
d = 13 2/4 = 13 1/2 = 13.5 miles
d/3 = 13.5/3 = 4.5 hours
d/9 = 13.5/<u>9 = 1.5 hours</u>
Total 6 hours
I hope this is the right interpretation.
