Answer 2

Answer:

You burn 265 calories running and then 7 calories per minute swimming.

Your friend burns 273 calories running and then 11 calories per minute swimming.

Let us assume that both of you swim for x minutes.

Calories burnt by you = $265+7x$

Calories burnt by your friend = $273+11x$

Difference between both = $273+11x-(265+7x)$

= $273+11x-265-7x$

= $8+4x$

Hence, difference can be shown using $8+4x$.
