The ratio is calories per minute, or cal/min. The value is 10 cal/1 min. Setting up a ratio equality to find the change at a different time we have: 10cal/1min=?cal/20min. Now we do the math - multiply both sides by 20 min: 20min⋅10cal/1min=?cal/20min⋅20min The minute dimensions cancel out, leaving us with 200cal=?cal. So, a 20-minute jog will use 200 calories.

We can create an equation for such. Say j is the time you jog, and c is the calories you burn.  We get the equation j=10c.  This asks, if we have 20j, what is the coefficient of c?   We take our original equation:  j=10c  We multiply both sides by 20:  20j=20⋅0=10c  20j=200c  So you burn 200 calories.
