Andy is scuba diving. He starts at sea level and then descends 10 feet in 21/2
minutes. How would you represent Andy’s descent as a unit rate? Express your answer as an integer.
Enter your answer in the box.
To represent Andy's descent as a unit rate, we divide the distance by the time:
10 feet / (21/2 minutes)
To further simplify, we can convert the mixed number to an improper fraction:
10 feet / (2/2 + 1/2 minutes)
10 feet / (3/2 minutes)
To divide by a fraction, we multiply by its reciprocal:
10 feet * (2/3 minutes)
This gives us the unit rate of descent as 20/3 feet per minute.
