The formula
d=1.1t^(2)+t+1
expresses a car's distance (in feet) north of an intersection,
d
, in terms of the number of seconds
t
since the car started to move. a. As the time
t
since the car started to move increases from
t=2
to
t=5
seconds, what constant speed must a truck travel to cover the same distance as the car over this 3-second interval?
◻
feet per second
◻
b. As the time
t
since the car started to move increases from
t=7
to
t=7.1
seconds, what constant speed must a truck travel to cover the same distance as the car over this 0.1 -second interval?
