You hungrily remove frozen meat from the fridge. Its temperature is 28 degrees Fahrenheit. Its temperature is increasing by 3 degrees Fahrenheit
every five minutes. What will its temperature be after 30 minutes?

46 degrees Fahrenheit
You know it increased every five minutes so 30 divided by 5 is 6. That’s 6 times it has increased. 6 multiplied by 3 which is how many degree it’s increased each increment gives you 18. That’s the told it’s increased by 30 minutes. Then add the original temperature which was 28 to 18 which gives you 46.
