I'm still needing some help knowing how to work this proportion.
A glacier moves about 12 inches every 36 hours. About how far does the glacier move in 1 week?
Is it 12 in / 36 hrs = x/week (in hours)
Right.
Cross multiply and solve for x.
Thanks so much that helped alot.
That is correct. I am solving this problem rough now myself.. And was looking to help others (: you got it !
To solve this proportion, you can use the concept of equivalent ratios.
Given that the glacier moves 12 inches in 36 hours, we can express this as a ratio:
12 inches / 36 hours = x inches / 1 week
To solve for x, we need to convert the 1-week unit from hours to match the given 36 hours.
There are 24 hours in a day, and 7 days in a week, so 1 week is equivalent to 24 hours * 7 days = 168 hours.
Now, we can rewrite the proportion as:
12 inches / 36 hours = x inches / 168 hours
To find x inches, we can cross-multiply and solve for x:
12 inches * 168 hours = 36 hours * x inches
2016 inches = 36x
Now divide both sides of the equation by 36 to isolate x:
2016 inches / 36 = x
Simplifying this equation gives:
56 inches = x
Therefore, the glacier moves about 56 inches in 1 week.
