mote1985 [20]

Answer:

6:38am

Step-by-step explanation:

From the question we are told that

Average speed V_{avg}=10km/h

Distance traveled d=7km

Generally the velocity across a distance is mathematically given given as V=d/t

10=\frac{7}{t}

t=0.7h\\t=42minutes

Therefore

7:20-42 minutes =6:38am

1a) f(x) = I x+2 I. This is a piece-wise graph ( V form)
      x = 0 →f(x) =2 (intercept y-axis)
      x = -2→f(x) = 0 (intercept x-axis)
      x = -3→f(x) = 1 (don't forget this is in absolute numbers)
      x = -4→f(x) = 2 (don't forget this is in absolute numbers)
Now you can graph the V graph

1b) Translation: x to shift (-3) units and y remains the same, then
      f(x-3) = I x - 3 + 2 I = I x-1 I
     the V graph will shift one unit to the right, keeping the same y. Proof:
     f(x) = I x-1 I . Intercept x-axis when I x-1 I = 0, so x= 1
