Let
x-------> the time in hours
y------> the distance in miles
we know that
speed=distance/time-------> speed=y/x-------> equation 1
speed=5.5 miles/hour------> equation 2
equate equation 1 and equation 2
y/x=5.5--------> y=5.5*x---------> this is the equation for the problem
the distance that Andrew jogs will depend on the time spent
examples
a) if he runs for 2 hours,
then
x=2 hours
y=5.5*2-------> y=11 miles
b) if he runs for 3 hours,
then
x=3 hours
y=5.5*3-------> y=16.5 miles
c) if he runs for 30 minutes
then
30 minutes=0.5 hours
x=0.5 hours
y=5.5*0.5-------> y=2.75 miles
