Answer:
Yes, vectors u and v are equal.
Step-by-step explanation:
We need to check whether vectors u and v are equal or not.
If the initial point is
and terminal point is
, then the vector is

Vector v with an initial point of (-5,22) and a terminal point of (20,60).

..... (1)
Vector u with an initial point of (50,120) and a terminal point of (75,158).

.... (2)
From (1) and (2) we get

Therefore, vectors u and v are equal.
Answer:
Distance of Tunnel is 500 meters + Train travel rate is 20 meters per second = 25 seconds to pass through the tunnel only therefore the outstanding balance of 35 seconds x 20 meters per second =600 meters Train
Step-by-step explanation:
Total of length of train 600 meters and tunnel (500 meters) is 1,200 meters +30 seconds = TR of 20 meters per second
