The runner completes 1/4 of a 5-mile race every 8 minutes. This means that in 1 minute, the runner completes 1/4 divided by 8, or 1/32 of the race. In 16 minutes, the runner would complete 16 times 1/32, which is 16/32 or 1/2 of the race.
Therefore, the runner can go 1/2 of 5 miles, which is 2 1/2 miles in 16 minutes.
The correct answer is:
2 1/2 miles
Therefore, the runner can go 1/2 of 5 miles, which is 2 1/2 miles in 16 minutes.
The correct answer is:
2 1/2 miles

The water tank decreases by 10 gallons every 3 hours, so it decreases by 10/3 gallons per hour.
In 6 days, there are 6 times 24, or 144 hours.
Therefore, the total change in the amount of water in the tank after 6 days would be 144 times (10/3) gallons.
Calculating this, we get 144 * (10/3) = 480 gallons.
The correct answer is:
480 gallons
In 6 days, there are 6 times 24, or 144 hours.
Therefore, the total change in the amount of water in the tank after 6 days would be 144 times (10/3) gallons.

The recipe calls for 1/3 of a container of yogurt, which has 150 calories. The recipe makes 4 servings.
To find the number of calories per serving, we need to calculate (1/3) times 150 divided by 4.
Therefore, the correct set of calculations is:
1/3×150÷4
The correct answer is:
Start Fraction 1 over 3 End Fraction times 150 divided by 4
