Let's convert everyone into feet per second (ft/s)
Jessica : 8ft/s
Debbie: 637ft/49s = 13ft/s
Katie: 5280ft/511s = 10.33ft/s (1 mile equals 5280 feet)
Tony: 550ft/60s = 9.16ft/s (1 mile equals 5280 feet, 1 minute equals 60 seconds)
Jessica runs the fastest.

We are given the range of the data that is from 2.35 grams to 4.75 grams- we can call these two the lower and upper llimits respectively. In this case, to find the first class limits, we have to divide the range into 12. The range is 2.40 grams made up of 12 parts of 0.2 grams. The first class hence limits are
lower: 2.35 g
upper: 2.35+0.2 =2.55 g
Answer:
its the last one if not that then the 3rd one
