Kevin and Kara are in a pancake-eating contest. Kevin can eat three pancakes per minute, while Kara can eat \(3\frac{\mathrm{1} }{\mathrm{2} }\) pancakes per minute. How many total pancakes can they eat in 10 minutes?

Detailed Explanation

If Kevin eats 3 pancakes in one minute, you know he eats 3(10) = 30 in 10 minutes. If Kara eats \(3\frac{\mathrm{1} }{\mathrm{2} }\) per minute, she eats 3.5 × 10 = 35 in 10 minutes. Add 30 + 35 = 65 and you have your answer.
