Svetllana [295]
We define the spaces of the man and the woman's independent arrivals.
In this case, 
f(man) = 1 (45-15) = 1/30
f(woman)=1/(60-0)= 1/60
f(man)*f(woman) = 1/1800

Probability = P 
P (man-woman)< 5 = 1/1800* integral of (y ) with limits of (x+5) and (x-5) from 45 to 15. 
P (man-woman) <5 = 1/6
