Final answer:
Nikhil walked 2.4 times as far as Amara; while Amara walked 5/8 of a mile, Nikhil walked 1 1/2 or 1.5 miles, which is equivalent to 12/8 of a mile.
Step-by-step explanation:
To find out how many times farther Nikhil walked than Amara, we need to compare the distances they each walked. Amara's walk is 5/8 of a mile, and Nikhil's walk is 1 1/2 (or 1.5) miles. To compare these, we need to convert Nikhil's walk into the same unit of measurement as Amara's, which is in eighths of a mile.
Since 1 mile is 8/8 of a mile, Nikhil's walk of 1 1/2 miles is the same as 12/8 of a mile (1 mile is 8/8, and 1/2 mile is 4/8, so together they are 12/8). Now we can compare the two distances: Nikhil walked 12/8 mile while Amara walked 5/8 mile.
To find out how many times farther Nikhil walked, we divide Nikhil's distance by Amara's distance: 12/8 ÷ 5/8 = 12/5, which simplifies to 2.4.
So, Nikhil walked 2.4 times as far as Amara.
