Answer: 178 calories
Explanation:
From the question, we are informed that Jessica weighs 125 lbs and that she rode a bike at 17 mph for 25 minutes. It should be noted that 17 mph is thesame as 0.057 cal/lb/min.
Therefore, the calorie cost of this activity will be:
= 0.057 x 125 = 7.125
We then multiply 7.125 by the number of minutes used. This will be:
= 7.125 x 25
= 178 calories
