I will give the person 10 points
1.assume a 150 pound person bicycling at 12 mi/h burn 410 calories/h, how much will a 120 pound person burn.
2.assume a 150 pound person bicycling at 12 mi/h burn 410 calories/h, how much will a 180 pound person burn.

I believe that is just a simple ratio problem. 150:410 as 120:?
the answer is 410X120/150=410X4/5=82X4=328. the other answer is half again more, or 492, I think.

(1)
120/150 @ 12mi/h = 4/5(410) = 328 Calories/h.
(2)
180/150 @ 12mi/h = 6/5(410) = 492 Calories/h.
It costs energy to push weight. It's likely the heavier person will burn up more calories per unit of body weight then the lighter person for the same speed and distance and this is not taken into consideration here. The body weight proportional factor is not given.

1. Set a proportion.
150 lbs / 410 calories = 120 lbs / x calories
I'm assuming the rate of calories burn is the same no matter the weight, or it would have been specified in the problem.
Cross multiply.
150x = 410(120)
150x = 49200
x = 328
A 120 pound person would burn 328 calories/hour.
2. Set another proportion.
150 lbs / 410 calories = 180 lbs / x calories
150x = 410(180)
150x = 73800
x = 492
A 180 pound person would burn 492 calories/hour.

A 120 pounds person would burn 328 calories
and A 180 pounds person would burn 492 calories
if we assumed that there's proportionalism!

the 120 pound person will burn 328 calories/h
the 180 pound person will burn 492 calories/h
those answers r correct if we suppose that all of them ride at the same speed & burn at the same rate

i think number one is 328 calories and number two is 492 calories. here is what i did:
120 / 150 = 0.8
410 * 0.8 = 328
180 / 150 = 1.2
410 * 1.2 = 492

assuming a one to one correspondance the above answers seem to be perfect
