Step-by-step explanation:
Distance Formula: 
Simply plug in your 2 coordinates into the formula to find distance <em>d</em>:






1st day: 1 1/2 hours
2nd day: half of first day = 1/2 * 1 1/2 hours
3rd day: 2 1/2 times as long as first day: 2 1/2 * 1 1/2 hours
1 1/2 + 1/2 * 1 1/2 + 2 1/2 * 1 1/2 =
= 3/2 + 1/2 * 3/2 + 5/2 * 3/2
= 3/2 + 3/4 + 15/4
= 6/4 + 3/4 + 15/4
= 24/4
= 6
