One hour after Sid started walking the 60 miles from X to Y, James started walking from X to Y as well. Sid walks 3 miles per hour and James walks 1 mile per hour faster than Sid . How far from X will James be when he catches up to Sid ?	Choose the correct answer
A) 8 miles  B) 9 miles  C) 12 miles  D) 11 miles  E) 13 miles
First, determine how far Sid has walked in the one hour. he has walked three miles which means he is three miles ahead of James when he sets off. James walks at four miles/hour which means that every hour, james will get one mile closer to Sid . If he gets one mile closer every hour, it will take him three hours to catch up to him which means he travels 3hours * 4 miles/hour = 12 miles and he travels 4 hours * 3 miles/hour = 12 miles. He will be 12 miles from X when he catches up to her.   A slightly different way to solve...   We don't know how long they will walk before they catch up to one another but we do know that A walks for one hour more than J. J = T and A = T+1. We are looking for the distance at which they meet up which means the distance will be the same. D=r*t so,   r*t (james) = r*t (Sid )   r*(t) = r*(t+1)   4t = 3t+3   t=3   d=r*t   d=4*3=
