To determine how many miles per minute Justin runs, simply divide 5 miles by 45 minutes.
We can use the short division method for this.
Since 5 has fewer digits than 45, we will add a zero on 5 with a decimal point as a connector.
Then, multiply 1 by 45 and subtract it from 50.
After subtraction, the result is 5. Since the result is 5 and the number of digits is again fewer than the divisor, we will add another zero to the dividend.
