If marissa left her apartment at 7:00am riding her bike at 12 mi/h. At 7:30 am her roommate set off after her riding her moped at 18 mi/h. How long did it take marissas roommate to find marissa

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'm sure goog can you get that answer
