Question

Hannah went on a bike ride on Saturday and Sunday every weekend in November. She recorded the number of miles she rode each time. The following line plot represents the number of miles she recorded. What is the difference between the longest and shortest number of miles?

Answer 1

Looking at the line plot, the longest number of miles is 50, and the shortest is 48 1/4.

Calculating the difference, we have:

$\begin{gathered} 50-48\frac{1}{4} \\ =50-(48+\frac{1}{4}) \\ =50-48-\frac{1}{4} \\ =2-\frac{1}{4} \\ =\frac{8}{4}-\frac{1}{4} \\ =\frac{7}{4} \\ =1\frac{3}{4} \end{gathered}$

Therefore the correct option is the third one.
