Answer:
[tex]5.75\frac{miles}{hour}[/tex] or [tex]5\frac{3}{4}\frac{miles}{hour}[/tex]
Step-by-step explanation:
we know that
The speed is equal to divide the distance by the time
Let
s------> the speed in miles per minute
y------> the distance in miles
x-------> the time in minutes
so
[tex]s=\frac{y}{x}[/tex]
In this problem we have
[tex]y=4.6\ miles[/tex]
[tex]x=48\ minutes[/tex]
substitute
[tex]s=\frac{4.6}{48}=0.0958\frac{miles}{minute}[/tex]
Convert to miles per hour
[tex]0.0958\frac{miles}{minute}=0.0958*60=5.75\frac{miles}{hour}[/tex]
Convert to mixed number
[tex]5.75\frac{miles}{hour}=5+0.75=5\frac{3}{4}\frac{miles}{hour}[/tex]
