The function d(x) represents distances traveled by a train traveling at 80 mph during t hours after 1:00 pm. What does d(5) -d(2) represent A.the distances traveled by the train by 5:00 pmB.the distances traveled by the train for 3 hoursC.The change in distances between 2:00 pm and 5:00 pmD.The change in distances between 3:00 pm and 6:00 pm
Accepted Solution
A:
Hi, d(5) is the distance traveled by the train after 5 hours. d(2) is the distance traveled by the train after one hour. So, d(5)-d(S) is the the change in distances between 2:00 pm and 5:00 pm.
