I travel 1/10 mile in 1/2 second. how many can i travel in one second

2/10 miles

Step-by-step explanation:

2 x 1/10 = 2/10

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

milk=16 large

soda=280 kids

juice box=82 regular

63 soda +63 regular

124 large total
