Kevin and Kara are in a pancake-eating contest. Kevin can eat three pancakes per minute, while Kara can eat four pancakes per minute. How many total pancakes can they eat in 10 minutes?

70 pancakes


If Kevin eats 3 pancakes in one minute, you know he eats 3(10) = 30 in 10 minutes. If Kara eats 4 per minute, she eats \(4 \times 10=40\) in 10 minutes. Add 30 + 40 = 70 and you have your answer.
