Ted bikes 30 minutes per day 4 days per week. If Ted
burns, on average, 5 calories per minute while biking,
about how many calories will Ted burn biking during a
3-week period?
F.
1800
G.
1200
H.
800
J.
600
K.
400
Ted bikes for a total of 30 minutes per day x 4 days per week = <<30*4=120>>120 minutes per week.
Ted will burn a total of 5 calories per minute x 120 minutes per week = <<5*120=600>>600 calories per week.
During a 3-week period, Ted will burn a total of 600 calories per week x 3 weeks = <<600*3=1800>>1800 calories.
Therefore, Ted will burn about 1800 calories biking during a 3-week period.
The answer is F. 1800.
