A person hikes cross-country for 30 minutes and burns 144 calories. About how many calories will that person burn in 55 minutes of cross-country hiking? Round your answer to the nearest calorie

Question

this is a word problem on a math sheet (not homework) that I am trying to figure out but can't exacly remember how.

Answer 1

If the person burns 144 cals in 30 minutes, he/she burns 144/30 cals in one minute by proportion.

So in 55 minutes he/she burns 55×144/30=11×144/6=11×24=264 calories.
