Answer 1

div {
    width: 70px;
    -webkit-transition: .5s all;   
    -webkit-transition-delay: 5s; 
    -moz-transition: .5s all;   
    -moz-transition-delay: 5s; 
    -ms-transition: .5s all;   
    -ms-transition-delay: 5s; 
    -o-transition: .5s all;   
    -o-transition-delay: 5s; 
    transition: .5s all;   
    transition-delay: 5s; 
}

div:hover {
    width:130px;
    -webkit-transition-delay: 0s;
    -moz-transition-delay: 0s;
    -ms-transition-delay: 0s;
    -o-transition-delay: 0s;
    transition-delay: 0s;
}

This will trigger the mouseover state right away, but wait 5 sec till the mouseout is triggered.

Answer 2

transition can be declared as

transition: .5s all 5s

(shorthand, the first number is duration, the second number is delay) then you don't need the separate transition-delay

sorry, can't add as a comment as I don't have enough points
