Observe the table.
The function is an increasing function with in the time interval 
.
Upper estimation is the approximation by taking right end points with subintervals 
and
Lower estimation is approximation by taking the left end points subintervals.
In the table, time interval is divided into six sub intervals.
Therefore, the number of subintervals 
.
Width of the each interval :
.
Lower estimate :
Left end points are 
and 
.
Lower estimate for distance travelled in 
seconds is
Lower estimate for distance traveled in 
seconds is 
ft.
Right end points are 
and .
Upper estimate for distance travelled in seconds is
Upper estimate for distance traveled in seconds is 
ft.
Lower estimate for distance traveled in seconds is 
ft.
Upper estimate for distance traveled in seconds is 
ft.
