Speed of an object is defined by the expression → Speed = [tex]\frac{\text{Distance}}{\text{Time}}[/tex]
Jen's speed is [tex]2\frac{2}{5}[/tex] mph.
Distance traveled by Jen = [tex]\frac{1}{5}[/tex] mile
Time taken by Jen to reach her friend's house = 5 minutes
= [tex]\frac{5}{60}[/tex] hours
By using the expression of speed,
Speed of Jen = [tex]\frac{\frac{1}{5} }{\frac{5}{60} }[/tex]
= [tex]\frac{1}{5}\times \frac{60}{5}[/tex]
= [tex]\frac{12}{5}[/tex]
= [tex]2\frac{2}{5}[/tex] mph
Therefore, Jen's speed is [tex]2\frac{2}{5}[/tex] mph.
