Then subtract the calories Corey ate to find the net calories Cary burned: 450 calories - 200 calories = 250 calories. So the final answer is 250. <hau> Da farko, ka gano adadin kuzari da tafiya ta ƙone ta wajen ninka adadin kuzari da aka ƙone a kowace mil da yawan mil da Cary ya yi tafiya: mil 3 * 150 calories / mil = 450 calories.
