Distance = speed * time
for curtis d = st = 6t (where t is the time that he walks)
sean walks 20 seconds longer than curtis so we have the equation
d = s(t+20) = 5(t+20)
as the distances are the same we have
So sean has walked 100+20 = 2
6t = 5(t+20)
6t = 5t + 100
t = 100
so Sean walks 120 seconds when they had both walked the same distance.
The area of any triangle is A = (1/2) (base) (height).
If the right triangle is not sitting
on its hypotenuse, then one leg
is the base, and the other leg is
the height: A = (1/2) (base leg) (height leg) .
If the triangle is isosceles, then
the legs are equal: A = (1/2) (either leg)²
You said the area is 18 in²: 18 in² = (1/2) (leg²)
Multiply each side by 2 : 36 in² = leg²
Square root each side: 6 in = leg
When you open up a cube you have a
sideways cross shape with 6 squares
