This question can be solved using relative speed. The 2 people are moving towards each other. This means they are covering (v1 + v2) miles/hour between them every hour
Total distance between them at start= 55 miles
Distance covered together when they are just 11 miles apart = 55-11 = 44 miles
So they covered 44 miles, with a speed of 12+10 = 22
Time taken = 44/22 = 2 hours
Jane and Jill move towards each other from two towns that are 55 miles apart. Jane?s speed is 12 miles per hr and Jill?s speed is 10 miles per hr. After how much time will they be 11 miles apart?
