Answer:
I could be wrong, but I think it's x=12
First of all, we know that Emily travels 3/4 of a mile in 4 minutes and 30 seconds (i.e. 9/2 of a minute). So, her current velocity is
of a mile per minute.
At this speed, it takes

minutes to travel 3.42 miles.
Since she left at 8.25, she will arrive at about 8.46, so she's on time for school.
Ok so the value of x is 6 those lines on the 6 and x lines means that they are congruent. Then to figure out y you would use Pythagorean theorem 6^2+6^2
36+36=72
Square root 72 is about 8.5
8.5 would be y. Let me know if this is right and if this helps
