how far is the crease from the wicket
Crease (cricket) The origin of creases is uncertain but they were certainly in use by the beginning of the 18th century when they were created by scratch marks, the popping crease being 46 inches in front of the wicket at each end of the pitch. In the course of time, the scratches became cuts which were an inch deep and an inch wide. The cut was in use until the second half of the 19th century.[1] Sometime during the early career of Alfred Shaw, he suggested that the creases should be made by lines of whitewash and this was gradually adopted through the 1870s.[2]
Run out The batsman can be judged run out when he is closest to the end where the wicket has been put down by the opposition. The runs completed before a Run out are still scored by the batsman and his team. The bowler does not get credit for the wicket.
Test cricket After 80 overs, the captain of the bowling side may take a new ball, although this is not required.[32]The captain will usually take the new ball: being harder and smoother than an old ball, a new ball generally favours faster bowlers who can make it bounce more variably. The roughened, softer surface of an old ball can be more conducive to spin bowlers, or those using reverse swing. The captain may delay the decision to take the new ball if he wishes to continue with his spinners (because the pitch favours spin). After a new ball has been taken, should an innings last a further 80 overs, then the captain will have the option to take another new ball.
