Answer:

f(t) = 160t,

d = f(t)

The function that relates the distance traveled d to the time t is:

f(t) = 160t, where d = f(t)

Step-by-step explanation:

If the train travels 480 kilometers in 3 hours, then it will travel 160 kilometers in one hour:

d = 160t

Now we replace d by f(t) because d = f(t):

f(t) = 160t

for any given value of t, d will be equal to t multiplied 160 times

Which fraction is greater 9/12 or 1/3
ValentinkaMS [17]
We need to first find a common denominator. This means that we need the 12 and the 3 to be the same number. We can change the 1/3 into 4/12 and see that 9/12 is larger than 4/12.
