Question

Tow buses are moving in opposite direction with velocities of 36km/hr and108km/hr. Find the diatance between them after 20 minutes

Answer 1

Answer:

48 km.

Step-by-step explanation:

Distance = Speed * Time.

Here the speed is relative. As the buses are moving in opposite direction the relative velocity of Bus 2 w.r.t to Bus 1 is 36+108 = 144 km/hr.

Time = 20 minutes = 20/60 hour = 1/3 hour.

Thus distance = 144 * 1/3

                       = 48 km.
