Answer:

D_{t} =95t

Step-by-step explanation:

A train was travelling with a constant speed.

As given in the table at time t = 1 hour, distance covered = 95 miles.

Similarly at time t = 2 hours distance covered = 190 miles

so difference = 190 - 95 = 95 miles

When we calculate the difference in the distances traveled at time t = 3 and t = 2

Distance covered = 285 - 190 = 95 miles

Now we are confirm that distance traveled d in t hours is representing an arithmetic sequence.

Explicit formula of an arithmetic sequence is represented by

D_{(t)}=D_{0}+(t-1)d

Where D_{t} =95 miles

and d = 95 miles  [ common difference ]

so D_{t} =95 + (t-1)95

        = 95 + 95t - 95

D_{t} =95t

Expression will be D_{t} =95t

Answer: d = 95t

Step-by-step explanation: if it takes one hour to travel 95 miles, then the distance will be 95 * time
