Answer:
0.117 mile/minute
Step-by-step explanation:
We are given that a runner ran distance=[tex]2\frac{1}{3}[/tex] of a mile.
Time taken by runner=20 minutes.
We have to find the average speed of runner.
Average speed =[tex]\frac{distance}{time}[/tex]
Distance=[tex]2\frac{1}{3}=\frac{7}{3}miles[/tex]
Substitute the values in the formula then, we get
Average speed=[tex]\frac{\frac{7}{3}}{20}[/tex]
Average speed=[tex]\frac{7}{3\times 20}=\frac{7}{60} mile/minute[/tex]
Average speed=[tex]0.117[/tex] mile/minute
