Question

Jessica is going for a walk. She takes 3 hours to walk 7.5 miles. What is her speed?

Answer 1

Speed, s, can be calculated using the formula;

`\begin{gathered} s=(d)/(t) \\ \\ \text{ Where;} \\ d=distance,t=time \end{gathered}`

Thus;

`\begin{gathered} d=7.5miles,t=3hours \\ \\ s=(7.5miles)/(3hours) \\ \\ s=25(miles)/(hour) \end{gathered}`

ANSWER: Her speed is 25 miles per hour.
