Describe the difference between the set of whole numbers and the set of natural numbers?
2 answers:
The set of counting numbers is called the set of natural numbers.
(1, 2, 3, 4, 5, 6, 7, 8, 9, 10)
When we include 0 in the set of natural numbers, the new set is called whole numbers.
(0, 1, 2, 3, 4, 5, 6, 7)
All natural numbers are included in the set of whole numbers. We can represent the relationship between these two sets of numbers using a diagram.

Alright, lets get started.
Roger can run one mile in 18 minutes.
Jeff can run one mile in 15 minutes.
Suppose in x minutes, they both will catch up.
Roger runs in 18 minutes = 1 mile
So, Roger will run in 1 minute = miles
So, Roger will run in x minutes = miles
Jeff runs in 15 minues = 1 mile
So, Jeff will run in 1 minute = mile
As Jeff gives roger a 1 minute head start, means Jeff will have x-1 minute time to run
So, Jeff will run in (x-1) minute =
As both are cathing up means they both runs same distance, means
Cross Multiplying
x = 6 minutes
So for calculating distance =
Distance = miles
It means it will take 1/3 or 0.33 miles before jeff catches up to roger. : Answer
Hope it will help :)
