Answer:
1/9
Step-by-step explanation:
First lets remember the equation
Speed = DIstance/Time
Lets figure out the first part, her speed, or rate.
Lets plug in now.
Speed= 300/6
Speed= 50 mph.
Now lets do the second part.
50= 450 x T
Solve the equation by taking 450 to the other side.
we get 50/450=T
Which becomes 1/9 when we simplify.
Hope this is the brainliest answer you come across :)
