Answer:
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.
