Oscar is training to compete in a cross country meet at his school in a week. He runs a total of 7 miles and 84 minutes. What is the unit rate of minutes per mile?
To find the unit rate of minutes per mile, we need to divide the total number of minutes by the total number of miles.
$\frac{84\text{ minutes}}{7\text{ miles}} = 12\text{ minutes per mile}$
Therefore, the unit rate of minutes per mile is $\boxed{12}$.
To find the unit rate of minutes per mile, you need to divide the total number of minutes by the total number of miles. In this case, Oscar ran a total of 7 miles in 84 minutes.
To find the unit rate, divide the total number of minutes (84) by the total number of miles (7):
84 minutes รท 7 miles = 12 minutes per mile.
Therefore, the unit rate of minutes per mile is 12 minutes.
To find the unit rate of minutes per mile, we need to divide the total number of minutes by the total number of miles.
The given information states that Oscar runs a total of 7 miles in 84 minutes. To calculate the unit rate, divide the number of minutes by the number of miles:
Unit rate = Total minutes / Total miles
Unit rate = 84 minutes / 7 miles
To simplify the calculation, we divide both the numerator and denominator by the greatest common divisor of 84 and 7, which is 7:
Unit rate = (84 minutes / 7 miles) / (7 miles / 7 miles)
Unit rate = (84/7) minutes/mile
Unit rate = 12 minutes/mile
Therefore, the unit rate of minutes per mile is 12 minutes/mile.
