Some people enjoy this type of math the best, i.e., Word Problems, while others have a little more difficulty with it. The trick is to read the question several times and then break it down. Make certain you understand when you are adding, subtracting, multiplying, dividing or doing a combination of calculations. You have the skills already so now let’s put those skills into practice.
Take a look at the following ten word problems and see if you can work the problems and find the solutions.
Adult: 72 x 60 (minutes) = 4,320 (beats per hour) x 24 (hrs.) = 103,680 beats
Child: 84 x 60 (minutes) = 5,040 (beats per hour) x 24 (hrs.) = 120,960 beats
120,960 - 103,680 = 17,280 more beats per day
Solution: The 10 year old’s heart beats 17,280 more beats per day than the average adult heart
