Please help in this question!! An ant can pass straight across a field in 3 hours with a speed of 0.2 mph. How long will it take the ant to cross the field at a speed of 0.1 mph?
Let t be the time the ant spent going at a speed of 0.1 mph.
Equation: ___
It will take the ant ___hours if it moves at 0.1 mph.

6 hours.

Step-by-step explanation:

If the ant can do this in s hours with the speed of 0.2, then at 0.1 it will take double the origanel time wich will be 6 hours.

i leave the calculator work to you.

7. diameter 4 miles, circumference 4π miles

8. radius 0.2 miles, circumference 0.4π miles

[this is a bad problem because the actual radius of a car on the track is less than 0.2 miles so the answer is less than 0.4π miles]

9. radius 6 feet, circumference 12π feet

10. diameter 14 cm, circumference 14π cm

11. diameter 4.8 feet, circumference 4.8π feet

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)
