If you walk at a speed of 3 meters per second, how far will you walk in 11 seconds?

33 meters

Explanation:

if you walk 3 meters a second and you walk for 11 seconds to find the answer you will multiply.

seconds walked 1   2   3   4   5   6   7   8   9   10   11

meters walked   3   6   9   12  15 18 21  24 27 30 33

so basically you multiply 3 times 11 and get 33

what experimental evidence led scientists to change from the previous model to this one?
