Beyond the Answer
To determine if the typing rates form a proportion, we first find the typing rates for both you and your friend. You type 250 letters in 60 seconds, which translates to approximately 4.17 letters per second (250 ÷ 60). Your friend types 375 letters in 90 seconds, equating to about 4.17 letters per second as well (375 ÷ 90). Since both rates are equal, they indeed form a proportion!
A way to visualize proportions is through the classic example of sharing pizza slices! Suppose you both agree to split a pizza based on your typing speeds: if you both get a slice proportional to your rates, you’d find that you get exactly the same amount. So, whether you’re typing letters or munching on pizza, proportions can help you divide things fairly and equally!
