The speed is the distance covered by an object at a particular time. The unit rate of speed of Marjorie is 16 miles per hour.
The speed is the distance covered by an object at a particular time. Therefore, it is the ratio of distance and time.
[tex]\rm{Speed = \dfrac{Distance}{Time}[/tex]
Given that It took Marjorie 15 minutes to drive from her house to her daughter school, while the school was 4 miles away from her house. Therefore, the unit rate of speed of Marjorie is,
Speed = Distance / Time
= 4 miles / 15 minutes
= 4 miles / (15/60) hours
= 16 miles per hour
Hence, the unit rate of speed of Marjorie is 16 miles per hour.
