a train leaves delhi at 9 a . m . at a speed of 30 kmph . another train leaves at 2 p . m . at a speed of 42 kmph on the same day and in the same direction . how far from delhi , will the two trains meet ?
"d = 30 * 5 = 150 rs = 42 – 30 = 8 t = 150 / 8 = 18.75 d = 42 * 18.75 = 787.5 km answer : c"
multiply(divide(multiply(30, add(const_3, 2)), subtract(42, 30)), 42)
