Step-by-step explanation:

If

and

then

This is the linear function. To plot the graph of this function, find x- and y- intercepts:

x-intercept:

y-intercept:

Plot these two points on the coordinate plane and connect them with a straight line.

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
