Anna ate a cookie that was 142 calories. She wants to burn those calories during her workout. When she goes running she burns at a rate of 63 calories per mile. When she bikes she burns 240 calories in 3 miles. If she plans to travel 2 miles, should Anna run or bike to meet her goal? I want the answer and a detailed reason as to why u got that answer. first, one to get it correct is

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.

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2
