Answer:
Student-A:
[tex]speed=\frac{1}{9}[/tex] mile/min
Student-B:
[tex]speed=\frac{1}{8}[/tex] mile/min
Student-C:
[tex]speed=\frac{1}{10}[/tex] mile/min
Step-by-step explanation:
Student-A:
she can run 2/3 mile in six minutes
so,
total distance is [tex]\frac{2}{3}[/tex] miles
total time =6 min
we can use formula
speed=(total distance)/(total time)
[tex]speed=\frac{\frac{2}{3} }{6}[/tex]
[tex]speed=\frac{1}{9}[/tex] mile/min
Student-B:
she can run 1/2 mile in 4 minutes
so,
total distance is [tex]\frac{1}{2}[/tex] miles
total time =4 min
we can use formula
speed=(total distance)/(total time)
[tex]speed=\frac{\frac{1}{2} }{4}[/tex]
[tex]speed=\frac{1}{8}[/tex] mile/min
Student-C:
she can run 4/5 mile in 8 minutes
so,
total distance is [tex]\frac{4}{5}[/tex] miles
total time =8 min
we can use formula
speed=(total distance)/(total time)
[tex]speed=\frac{\frac{4}{5} }{8}[/tex]
[tex]speed=\frac{1}{10}[/tex] mile/min
