Answer:
3 1/5 ft
Step-by-step explanation:
We can set up a proportion:
, where x is how long the pants are in real life
Cross multiply:
x = (2 2/7) * (1 2/5)
It's easier if we have improper fractions, so convert the mixed numbers into improper fractions:
2 2/7 = 16/7
1 2/5 = 7/5
Now, put these back in:
x = (16/7) * (7/5) = 16/5 = 3 1/5
Thus, in real life, the pants would be 3 1/5 ft long.
Hope this helps!
We have the representation of this problem in the figure below. As we have a 10.3 mile race, then the equation is fulfilled as:
We know that there is <span>a water station that is twice as far from the starting line as from the finish line, then:
</span>
So:
∴
and
<span>Finally, the distance of the runner from the finish line is:
</span>
