i) You want to use . Your result will be in . To make the required conversion to the units given use:



ii) The area under the velocity function is two right triangles, a trapezoid and a rectangle. Then divide the area by 60 to convert the minutes to hours to get the result in km.

iii) Use

The unit conversion has been tricky for me. Its not x/216 its 1000x/60^3. Your left hand side seems to be ok. I had not the trapezoid (trapezium to non americans).

x/216 is equal to 1000x/60^3.
