Answer:
v = 0.166 [mm/min]
Explanation:
To solve this problem we must calculate the speed of each bus by means of the following formula that relates the displacement with time.
V = displacement / time
displacement = 250 [mm]
time = 5[min] = 300 [s]
Vx = 250/300 = 0.833[mm/min]
Vy = 300/300 = 1 [mm/min]
The relative velocity is the subtraction of the velocities, since the velocities are in opposite directions.
v = (1 - 0.833) = 0.166 [mm/min]
