Ray's favorite activity is taking a leisurely bike ride through the park after work. Suppose his bike has a flat tire, so he decides to go for a jog instead. Jogging burns 745 calories an hour. How long does he need to jog in order to burn off that same extra doughnut and large frozen latte that he ate that afternoon? The doughnut had approximately 320 calories, and the latte had 820 calories.
