Word Problem: finding calories, given weight

[Radar]

The question is:

When you exercise, the number of calories you burn is roughly proportional to your weight. Using your own weight and the information in the table below, write and solve a proporation to find the number of calories you would burn if you proformed one activity in the table below for 60 minutes.

Information from the table.

Calories burned during Exercise for a 150lb person exercising for walking for 60 minutes is 300.

My weight is 155.

Word Problem

First let me say thanks for the quick response. I looked at some of the other problems and saw a small time delay so I logged out for awhile. I wish now that I hadn't. Anyways.

I wish I could tell you the answer. I cannot figure out a formula to use to solve this problem. I'm not sure if I'm reading too much into it or not enough. I am not anking for the answer but a place to start.

Do I need to figure out, based on the information given, 150lbs,60 minutes, 300 calories, how many calories are burned per minute. If so do I use the 60 minutes burns 300 calories there fore 5 per minute. That doesn't sound right to me because it doesn't figure in the weight. But if I do the weight and calories, that doesn't seem right either.

I really could use a nudge in the right direction. I've got myself wrapped around the axle and at this point I'm confusing myself. Please help!

a. 150/300 = 155/x
150/300 = 155/x/x
150/300(x) = 155/x
1/2x = 155/1
2/1(155/1) = 310

b.

a. 150/300 = 155/x
150/300 = 155/x/x
150/300(x) = 155/x
1/2x = 155/1
2/1(155/1) = 310
b.

Yes. Why complicate it?
x/155 = 300/150
x/155 = 2
x = 310
