Two trains are moving on two perpendicular tracks with velocities of magnitudes 64 km/h and 48 km/h. Find magnitude of the relative velocity of second train with respect to first train.

Two trains are running in the same direction. The speeds of two trains are 5km/h and15 km/h, respectively. What will be the relative speed of second train with respect to first?

two train A and B are moving on parallel tracks with velocities of 60 kmh^(-1) and 90kmh^(-1) respectively but in oppiste directions. Find (i) the relative velocity of train A.w.r.t train B and (ii) the relative velocity of ground w.r.t tain A.

Two trains are moving in opposite direction of 60 km/hr and 90 km/hr . Their lengths are 1.10 km and 0.9 km respectively . The time taken by the slower train to cross the faster train in seconds is :

Two trains are moving in the opposite directions on parallel tracks at the speeds of 63 km/hr and 94.50 km/hr respectively. The first train passes a pole in 6 seconds whereas the second train passes a pole in 4 seconds. Find the time taken by the trains to cross each other completely?
