We have a table in the question and we have to approximate using the midpoint rule.
00:11
We have to find the distance using the midpoint rule.
00:17
So midpoint rule is given by m of n is equal to summation of n i is equal to 1.
00:32
F of m i into delta x where n is the number of intervals here we are taking n is equal to five and so delta x will be b minus a over n now what is b and what is a? a is the lower limit and p is the upper limit.
01:17
If you see the table, the table starts at t is equal to zero, means zero is our lower limit and it ends at t is equal to 100 second.
01:32
So 100 is our upper limit.
01:36
And n we have 5.
01:38
So delta x will be 100.
01:42
Minus 0 over 5 that is equal to 20 second but velocity is given in miles per hour so we have to convert this second into hour we can do it by dividing by 3 ,600 that will be equal to 0 .00 triple 5, triple 5, 5, 5, 5, 6...
