Question

5. Two buses X and Y started moving in opposite directions

from a point. After 5 minute Xcovered distance of 250mm
and y covered the distance of 300m. Calculate the relative
velocity.​

Answer 1

v = 0.166 [mm/min]

Step-by-step 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]
