(a)time since brakes applied (sec) 0 2 4 6 8 10
speed(ft/sec) 100 80 50 25 10 0
since the speed is dcreasing so it is a decreasing function.then lower estimation of the distance is
=[80+50+25+10+0](2)=330feet
and upper estimation of the distance is
=[100+80+50+25+10](2)=530feet
we can find the best estimation of the distance by taking theaverage of these estimations
that is the best estimation of the distance is =(330+530)/2=430feet
(b) since 430>400 then the skunk was hit by the car
