<span><span><span>12.5meters</span><span>5<span><span>meters</span><span>minute</span></span></span></span>=2.5minutes</span>
we can check it by saying...okay...if his speed was 5 meters per minute....and he walked for 2.5 minutes...does he walk 12.5 meters?
<span>5×2.5=12.5</span><span>
so yes it checks out :)</span>
At the beginning, the chances that the teacher will choose a student who has forgotten his lunch are 2/10, or 1/5.
If the teacher now chooses another student from the remaining 9 students, the chances of his choosing a student who has forgotten his lunch are 1/9, since one of the forgetful students has already been removed from the original group of 10 students, and there are only 9 in the group remaining.
The probability that both students forgot lunch is (1/5)(1/9), or 1/45.
the answer would be E because if you round answer E to 3mph and divide by 2 you get 1.5 and a hour is 60 minutes divide that by 2 and you get 30 minutes however you walked slightly slower so it would take 5 minutes longer.
