Answer:
Bike
Step-by-step explanation:
Anna should go biking because when she runs it goes 63 calories per mile, and 63*2 is just 126 and that does not meet the goal of 142 calories. However, in biking if she goes 3 miles she burns 240 calories, so 240/3=80 so that means 80 calories a mile. 80*2 miles makes 160 which is more than enough calories burnt.
Answer:
Anna Should bike
Step-by-step explanation:
Run:
When she runs she only burns 63 calories in an hour, since she wants to travel 2 miles, multiply 63 by 2 which equals 124 calories per two hours. 124<142, so running wouldn't burn 142 calories.
Bike:
when she bikes, she burns 240 calories per every 3 miles. you have to find how many calories she burns in 1 mile first. To do this you divide 240 by 3. This equals 80 calories every mile. Because she wants to travel 2 miles, multiply 80 by 2 to get 160 calories burned every 2 miles. since 180>160 she should take the bike.
