Answer:
22 feet (if the distance is in feet, and the time in seconds)
Explanation:
t = time
d = distance
To see if the mouse's distance is proportional to the time, you divide the distance with the time:
= 4
= 44
44 / 4 = 11
= 6
= 66
66 / 6 = 11 (the same as with 44 / 4. This means that the mouse distance and time is proportional)
Every second the mouse travels 11 feet.
And every other second the mouse travels 22 feet. (since (1, 11)*2 = (2, 22))
That may have been confusing, and if you have any questions, don't be afraid to ask them in the comments below!
Have a good day!
