A radar gun was used to record the speed of a racecar during the first 40 seconds while driving on a straight road. Use the chart to calculate the car's distance after 40 seconds using righthand sums. Is this an over or underestimate? Justify the answer.

This is the table of values

seconds 0 1 3 8 20 40
V(m/s) 0 45.2 96.3 178.2 254.3 350.5

    The table didn't turn out
    0, goes with 0 underneath.
    1 goes with 45.2
    3 goes with 96.3
    8 goes with 178.2
    20 goes with 254.3
    40 goes with 380.5
