Answer:

The truck travel must to have a constant speed of $22.06\ ft/sec$

Step-by-step explanation:

we have

$d=1.3t^{2}+t+2$

where

d expresses a car's distance in feet

t is the number of seconds

Find the distance d for t=8 sec

$d=1.3(8)^{2}+8+2=93.2\ ft$

Find the distance d for t=8.2 sec

$d=1.3(8.2)^{2}+8.2+2=97.612\ ft$

The total distance in this interval of 0.2 sec is

$97.612-93.2=4.412\ ft$

Find the speed of the car

Divide the total distance by the time

$4.412/0.2=22.06\ ft/sec$

therefore

The truck travel must to have a constant speed of $22.06\ ft/sec$
