Answer:
[tex]\frac{7}{88}\ \frac{miles}{hour}[/tex]
or
[tex]0.08\ \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
x ----> the distance
y ----> the time
so
[tex]s=\frac{x}{y}[/tex]
we have
[tex]x=7\ ft[/tex]
[tex]y=1\ min[/tex]
Remember that
[tex]1\ mile=5,280\ feet[/tex]
[tex]1\ hour=60\ minutes[/tex]
so
[tex]x=7\ ft=\frac{7}{5,280}\ mi[/tex]
[tex]y=1\ min=\frac{1}{60}\ h[/tex]
Find out the speed in miles per hout
[tex]s=\frac{(7/5,280)}{(1/60)}=\frac{420}{5,280}\ \frac{miles}{hour}[/tex]
Simplify
[tex]\frac{7}{88}\ \frac{miles}{hour}[/tex]
or
[tex]0.08\ \frac{miles}{hour}[/tex]
