A, C and D because the angles are named in order. Q=T R=U and so on
3 cards
1/4 = x/12 1/4 = 3/12
4 * 3 = 12
1 * 3 = 3
x = 3
Constant of Proportionality = d/t = 90/2 = 45 mph
In short, Constant of Proportionality would be: 45 miles per hour.
Here, d/t = 45
d = 45t
In short, Your Equation would be: d= 45t
Hope this helps!
