Answer:
60 feet
Step-by-step explanation:
The length of the diagonal can be found from the Pythagorean theorem.
d = √(15² +20²) = √(225 +400) = √625
d = 25
Then the distance Haley walks is ...
20 ft + 15 ft + 25 ft = 60 ft

Answer: 4900 (choice D)</h3>
===================================================
Work Shown:
1 km = 1000 m
3.5 km = 3500 m ............. multiplying both sides by 3.5
(70 paces)/(50 m) = (x paces)/(3500 m)
70/50 = x/3500
7/5 = x/3500
7*3500 = 5x .............. cross multiply
5x = 7*3500
x = (7*3500)/5
x = (7*5*700)/5
x = 7*700
x = 4900
Ann takes 4900 paces to walk 3.5 km
Run and nug is the answer
