Answer:
264 miles
Step-by-step explanation:
Using the relation ...
distance = speed · time
we can rearrange to get ...
speed = distance/time
We can choose to let d represent the distance we want to find. Then Jina's speed going to the mountains is d/6. Her speed coming home is then d/6+22. It takes Jina 4 hours at that speed to cover the same distance, so we have ...
d = 4(d/6 +22)
d = 2/3d +88 . . . . eliminate parentheses
1/3d = 88 . . . . . . . subtract 2/3d
d = 264 . . . . . . . . . multiply by 3
Jina lives 264 miles from the mountains.
