Answer:
5 miles
Step-by-step explanation:
1 mile per 17 minutes, the number of miles in 1 hour 25 minutes is the total time/the time it takes to walk a mile, 1 hour 25 minutes/17 minutes = 85/17 = 5 miles

Answer:
Answer:
x = √70
Step-by-step explanation:
The triangles shown are all similar, so the corresponding sides are proportional.
hypotenuse/long side = x/7 = (7+3)/x
Cross-multiplying gives ...
x^2 = 7(10)
x = √70
_____
You will note that the value of x (the long side) is the geometric mean of the long segment and the whole hypotenuse.
A similar "geometric mean" relation holds for the short side:
BC = √(CD·CA)
There is yet another "geometric mean" relation that holds for the altitude:
BD = √(CD·AD)
