Answer:
I think jillian will have to run 10 miles
Step-by-step explanation:
2 miles = 100 calories
in order to burn 500 calories
2 miles = 100 calories burned
4 miles = 200 calories burned
6 miles = 300 calories burned
8 miles = 400 calories burned
10 miles = 500 calories burned
NI = 45
IG=28
HG^2 = NI^2 +IG^2
= 45^2 +28^2
=2025+784
= 2809
HG=53
CosG = IG/HG
= 28/53
= 0.52
