Bart burns $800$ $800$ calories in his three-hour trip.

Explanation:

Bart burns $200$ $200$ calories in $0.75,$ $0.75,$ or $\frac{3}{4},$ $3/4,$ hours.

Let's simplify this ratio of $200 : \frac{3}{4}$ $200:3/4$ so we can see how many calories Bart burns in one hour. This will require multiplying both sides of the ratio by $\frac{4}{3} :$ $4/3:$

$200(4/3):(cancel3)/(cancel4)*cancel(4)/cancel(3)$

We end up with $800/3:1$ , meaning that every hour, $800/3$ calories are burned.

We now need an equation.

Let's denote the calories Bart burns by $C.$

Furthermore, let's denote hours kayaked by $h.$

$C=800/3h$ where $h$

Plugging in $3$ for $h,$ we get

$C=(800/cancel3)(cancel3)=800$

Bart burns $800$ calories in his three-hour trip.
