1 furlong = 1/8 mile
10 = 10/8 = 1 2/8 or 1.25

2nd one is D. 135 cubic feet, theres s feet in a yard, so divide the number of feet by 3 to get 45

so A or B, but I dont know because that math is decently hard.

I know is 105 miles/ 1 hour so 105 miles to feet, then 1 to 60 seconds.

Answer 20

I dunno lemme ask dude to look at it, @dude

Answer 21

were experiencing technical difficulty on that last one.

Answer 22

Yeah you can convert miles to ft

\(105mi\cdot \dfrac{5280ft}{1mi}=>554400ft\)

Now from hours to [minutes to] seconds
\(\dfrac{554400ft}{1h}\cdot \dfrac{1h}{60min}=>\dfrac{9240ft}{1min}\cdot\dfrac{1min}{60sec}=>154\)

I think you just missed hour-> min-> seconds

Answer 23

yes ur right, I went from hours to seconds. Thanks Dude
