269767 Two trains\(A\) and \(B, 100 \mathrm{~m}\) and \(60 \mathrm{~m}\) long, are moving in opposite directions on parallel tracks. The velocity of the shorter train is 3 times that of the longer one. If the trains take \(4 s\) to cross each other, the velocities of the trains are
269791 Two carsaretravelling in the same direction with a velocity of \(60 \mathrm{kmph}\). They are separated by a distance of \(5 \mathrm{~km}\). A truck moving in opposite direction meets the two cars in a time interval of 3 minute. The velocity of the truck is (in \(\mathrm{kmph}\) )
269792 A police van moving on a highway with a speed of\(30 \mathrm{kmph}\) fires a bullet at a thief's car speeding away in the samedirection with a speed of \(192 \mathrm{kmph}\). If the muzzle speed of the bullet is \(150 \mathrm{~m} / \mathrm{s}\), with what speed does the bullet hit the thief's car? (Note: Obtain that speed which is relevant for damaging the thief's car).
