A person who weighs 240 pounds burns 180 calories per mile of running. If a person burns thirty-six calories by running one mile, how much does the person weigh?

Respuesta :

I would assume the weight of the person burning 36 calories per mile would weigh 180 pounds.
240 / 180 = x / 36....240 lbs to 180 cal/mile = x lbs to 36 cal/mile
cross multiply
(180)(x) = (240)(36)
180x = 8640
x = 8640 / 180
x = 48 lbs <==
