Rate of change  = [ final distance -  beginning distance ] / [ final time - beginning time ]

 

a. Rate of change over the whole trip  =  Miles / Hours  = 350 / 8  = 43.75 mph

 

b.  Between 4th and 5th hour  =  [300 - 225 ] / [ 5 - 4 ] = 75 / 1  = 75 mph

     Between the  5th and 6th hour  = [300 - 300] / [ 6 - 5]  = 0 / 1  = 0 mph

     Between the   6th and 8th hour = [ 350 - 300 ] / [ 8 - 6 ]  = 50/2  = 25mph

 

c.  No....if they were....the line would have a constant slope....but it doesn't

 

d. No...for the same reason given in (c)
