Kenzo is driving his car along a road while his friend records the velocity of the car, , in km/h every minute over a 5-minute period. The table gives the velocity    at time    hours.
 

The distance covered by the car over the 5-minute period is given by

.

Use the trapezoidal rule and the velocity at each of the six time values to find the approximate distance in kilometres the car has travelled in the 5-minute period. Give your answer correct to one decimal place.  (2 marks)

The table gives the speed of a jogger at time in minutes over a  20-minute period. The speed is measured in metres per minute, in intervals of 5 minutes.

The distance covered by the jogger over the 20-minute period is given by  .

Use the Trapezoidal rule and the speed at each of the five time values to find the approximate distance the jogger covers in the 20-minute period.   (3 marks)

Five values of the function    are shown in the table.
 

Use the Trapezoidal rule with the five values given in the table to estimate
