2.25cm because the drawing is 1/2 the size of the object
I'm guessing "Franken Berry Fanatic Starry" like the cereal. That's what my research tells me.
The slope of the line is +2
this means that Jan runs 2 laps every 1 minute
The length is determined by multiplying the number of balls with the diameter. The answer that would come out of this is in units of centimeters.
L = (6.02 x 10^23 balls)(4 cm/ball)
L = 2.408 x 10^24 cm
Then, we use the proper conversion factor to convert centimeter to kilometer.
L = (2.408 x 10^24 cm)(1 m/100 cm)(1 km/1000 m)
L = (2.408 x 10^24)(10^5)
The answer to this item is 2.408 x 10^19 km.
