Jonathon wanted to know how far people could swim in 30 minutes. He collected data from 10 people about how many miles they coul
d swim in 30 minutes and obtained the following results:
0.25 0.80 0.75 0.93 0.24 0.50 0.75 0.98 0.35 0.85
What is the range of the data Jonathon collected?
A. 0.60
B. 0.64
C. 0.74
D. 0.75
If we know that our ratio is 4 cm: 5 km. We can find the unit rate of the scale. Which would be 0.8 cm: 1 km. After we find the unit ratio we can then multiply both sides by 4. (4 * 0.8) : (4*1) After simplifying we get the ratio of 3.2cm: 4 km.
