Question

edna likes to go for walks with her dog. this graph shows how long she spent on different walks. walking times how much total time did edna spend on the walks that took her exactly $1\frac{1}{2}$ hours to finish?

Explanation:

Step1: Count the number of walks at \(1\frac{1}{2}\) hours

There are 4 "X" marks at \(1\frac{1}{2}\) hours.

Step2: Calculate the total time

Each walk at \(1\frac{1}{2}\) hours contributes \(1\frac{1}{2}\) hours. So the total time is \(1\frac{1}{2}\times4\).
Convert \(1\frac{1}{2}\) to an improper fraction: \(1\frac{1}{2}=\frac{3}{2}\). Then \(\frac{3}{2}\times4 = 6\)

Answer:

6 hours
