3. Roger is running a 16 mile marathon. If he has ran 7 1/2 miles in the first 20 points 30 minutes and 4.5 miles in another 30 minutes. How much does he have left to run to finish the marathon? -4 4 4 1/3 21/4

Respuesta :

He has to run 4 miles to finish the marathon

Here, we want to calculate the number of miles left to finish the marathon

To get this, we shall be subtracting the distance he has ran from the total

kindly note that 1/2 is same as 0.5

Hence 7 1/2 miles is same as 7.5 miles

Mathematically, that would be;

16 miles - (7.5 miles + 4.5 miles)

= 16 miles - 12 miles

= 4 miles
