Hey there! I'm happy to help!
We see that the bike travels at 70 miles per hour. There are 5280 feet in one mile, so 70 miles is 369600 (70×5280).
We have 369600 in 1 hour, which is the same as 60 minutes. There are 60 seconds in a minute, so this means that there are 3600 seconds in an hour (60×60).
We have 369600 for 3600 seconds. We want to see how far the bike travels in one second, we simply divide 369600 by 3600.
369600÷3600≈102 2/3.
Now we multiply this by 25 for 25 seconds.
102 2/3×25=2566.7 (rounded to nearest tenth of a foot)
Therefore, in 25 seconds, the bike will have traveled 2566.7 feet.
Have a wonderful day! :D

Plug in 3 to x:
f(x) = 3³ - 7
Solve:
f(x) = 3³ - 7
f(x) = 3 · 3 · 3 - 7
f(x) = 9 · 3 - 7
f(x) = 27 - 7
f(x) = 20

Yes they do. Notice that for each step in x there a +4 in y. If you want an equation we can set it up with the inforation given
Yes theres a relationship because for every meter she runs it takes her 4 minutes for each.
