Q. The double number line shows how many meters a dragonfly can fly in 1 second.Which table represents the rate at which a dragonfly can fly?Choose 1 answer:(A) \begin{tabular}{|ll|}\hline Seconds & Meters \\\hline 8 & 225 \\12 & 300 \\20 & 550 \\\hline\end{tabular}(B) \begin{tabular}{|ll|}\hline Seconds & Meters \\\hline 3 & 75 \\5 & 125 \\10 & 250 \\\hline\end{tabular}
Check Rates Consistency: : Check if the rates in Table (A) are consistent.Calculate the rate for each pair of values.Rate for 8 seconds: rac{225 ext{ meters}}{8 ext{ seconds}} = 28.125 ext{ meters per second}.Rate for 12 seconds: rac{300 ext{ meters}}{12 ext{ seconds}} = 25 ext{ meters per second}.Rate for 20 seconds: rac{550 ext{ meters}}{20 ext{ seconds}} = 27.5 ext{ meters per second}.
Calculate Rates: : Notice the rates in Table (A) are not the same, which means the rate is not consistent.
Inconsistent Rates: : Check if the rates in Table (B) are consistent.Calculate the rate for each pair of values.Rate for 3 seconds: rac{75 ext{ meters}}{3 ext{ seconds}} = 25 ext{ meters per second}.Rate for 5 seconds: rac{125 ext{ meters}}{5 ext{ seconds}} = 25 ext{ meters per second}.Rate for 10 seconds: rac{250 ext{ meters}}{10 ext{ seconds}} = 25 ext{ meters per second}.
Check Rates Consistency: : Notice the rates in Table (B) are the same, which means the rate is consistent.
