Answer:
Therefore you have to run every mile in ~ 8 minutes.
Step-by-step explanation:
10 miles - 3 miles = 7 miles left.
1 hour 20 minutes - 24.7 minutes= 80 minutes - 24.7 minutes
= 55.3 minutes left
Therefore, you have 55.3 minutes left to run 7 miles. But since you want to finish in LESS than 1 hour and 20 minutes, subtract the .3.
So:
7 miles = 55 minutes
1 mile x minutes
x minutes= 55 x 1 ÷ 7 miles
x minutes = 7.85
x minutes = ~ 8 minutes
Therefore you have to run every mile in ~ 8 minutes.
Hope this helps!

The distance formula to calculate distance between two points (a,b) and (c,d) is given by :-
Now, the distance between(2, 5) and (5, 7) is given by :-
Hence, the distance between the points (2, 5) and (5, 7)
We need to find whole numbers not more than 4 digits
Not more than 4 digits means it can be a one digit, 2 digit, 3 digit and a 4 digit number
It is a whole number so we include 0
-----, ------- , -------, --------
First digit we can use numbers 0 to 9 so 10
For second digit we can use numbers 0 to 9 so 10
For third digit we can use numbers 0 to 9 so 10
For fourth digit we can use numbers 0 to 9 so 10
---10--, ---10---- , --10-----, ----10----
So 10* 10 * 10 * 10 = 10000
10000 whole numbers are there with not more than 4 digits
Answer:
The mean distance that Andrew runs per day is 4. 79 miles.
