Answer 2

hes right

Answer 3

how though ?

Answer 4

you could set this up as a ratio. First convert the minutes to seconds and then set up the ratio as such:

Answer 5

If it travels 15 feet per minute and you have 24 minutes, multiply 15 by 24 to get 360. Then 40 seconds is 2/3 of 1 minute. so 2/3 of 15 is 10, and ten you add 10 to 360

Answer 6

Convert speed from feet/minute into feet/seconds.

15 feet / mn = 15 feet / 60 sec

In 24 minutes 40 seconds, there are

24*60 + 40 = 1480 seconds

We now multiply speed by time to find distance

1480*15/60 = 370 feet

Answer 7

ohhh so you have to convert

Answer 8

yes

Answer 9

yes

Answer 10

24 minutes is 1440 seconds. Add that to the number of seconds you already have which is 40 to get a total of 1480 seconds. Your ratio then is this:
