a truck driver is d(t) = 400 − 70t miles from his destination after driving t hours. he drives at a constant rate.
(a) interpret the ordered pair (4, 120). when the driver has driven , he is incorrect: miles from his destination.
(b) after driving 2 hours, how far is he from his destination? mi
(c) how far did he go in his second hour of driving? mi

a. 4 and 120. b. 260 miles. c. 140 miles.

Step-by-step explanation:

d(t) = 400-70t.

a. (4,120) refers that with t=4 (when the driver has driven 4 hours), he is incorrect: 120 miles from his destination. d(4) = 400-70(4) = 400-280 = 120.

b. After driving 2 hours, that is in t=2, he is d(2)= 400-70(2) = 400-140 = 260 miles from his destination.

c. In his second hour of driving, that is in t=2 he is 260 miles from his destination, so he has driven 140 miles.
