Question

A boat P is moving at 40 km/hr and another boat Q is moving at 20 km/hr. Which one of the following is not
a possible value for their relative velocity-
(1) 10 km/hr
(2) 20 km/hr
(3) 30 km/h
(4) 40 km/h​

Answer 1

Answer:

Is the answer 10 km\hr

if yes then-

(1) with respect to a stationary object relative velocity of boat P=40km\hr

(2) similarly relative velocity of boat Q=20km\hr

(3) with respect.to each other their relative velocity=20+40\2=30km\hr

there fore the relative speed cannot be 10 km\hr
