To find the difference in height between the two positions of the parasail, we need to subtract the two heights.
The initial height of the parasail is \( \frac{1}{20} \) kilometers.
The height after 10 minutes is \( \frac{1}{50} \) kilometers.
-
First, we need a common denominator to perform the subtraction. The least common multiple (LCM) of 20 and 50 is 100.
-
Convert \( \frac{1}{20} \) to a fraction with a denominator of 100: \[ \frac{1}{20} = \frac{5}{100} \]
-
Convert \( \frac{1}{50} \) to a fraction with a denominator of 100: \[ \frac{1}{50} = \frac{2}{100} \]
-
Now subtract the two fractions: \[ \frac{5}{100} - \frac{2}{100} = \frac{5 - 2}{100} = \frac{3}{100} \]
So, the difference in height is \( \frac{3}{100} \) kilometers.
The correct response is:
3/100 kilometers
Start Fraction 3 over 100 End Fraction kilometers
