Answer 1

Wow thank you.!

Answer 2

wait were did it go

Answer 3

55 miles per hr

5280 ft per mile
3600 seconds per hr

(5280(55)) / 3600 = 290400/3600 = 80.67 ft per second (A)

===============
travels 80.67 ft per second
40 minutes = 2400 seconds

80.67/1 = x/2400 -- (80.67 ft to 1 sec = x ft to 2400 seconds)
cross multiply
x = 2400(80.67)
x = 193608 ft in 40 minutes (B)

I think I did the second part right...you might need to get a second opinion
