Answer:
The answer to your question is It will take 1 hour to find Marissa
Step-by-step explanation:
Data
Marissa time = 7:00 am speed = 12 mi/h
Roommate time = 7:30 am speed = 18 mi/h
Process
1.- Calculate the distance traveled by Marissa in 30 min (0.5 h)
d = vt
d = (12)(0.5)
d = 6 mi
2.- Write an equation to solve this problem
Distance traveled by Marissa = Distance traveled by the roommate
6 + vmt = vrt
- Substitution
6 + 12t = 18t
- Solve for t
6 = 18t - 12t
6 = 6t
t = 6/6
t = 1 h
I think A
Since the center of dilation is at A, only the A coordinate remains
The answer would be D, 75.
