Answer:
About 20.8 minutes
Step-by-step explanation:
TO solve this just think of it as a ratio. The number of potatoes goes on top and the time goes on bottom.
48
__
10
That is what the first one would look like. In the second one we know the number of potatoes but we are trying to find the time (x).
100
___
x
Take these two ratios and set them equal to each other.
Next you cross multiply (take 48 times x and 100 times 10).
48x=1000 Now divide by 48 and you have your answer.
About 20.8 minutes
