Accepted Solution

A:

lets t time and c the calories burned p pound burns

p= c/t

155lb=500cal/1h

1lb= 3500 cal

30-5 =25 min of workout 25/60= 5/12 hr

1/t=c/5/12

1 lb =3500 cal

500/1=c/5/12

c=208 cal

3500/t=208/(5/12)

3500/t=500

t= 7 min to burn 1 pound calorie

p= c/t

155lb=500cal/1h

1lb= 3500 cal

30-5 =25 min of workout 25/60= 5/12 hr

1/t=c/5/12

1 lb =3500 cal

500/1=c/5/12

c=208 cal

3500/t=208/(5/12)

3500/t=500

t= 7 min to burn 1 pound calorie
