Mark runs back and forth on a football field for a total of 3000 yards. How many miles did Mark run to the nearest tenth of a mi
gizmo_the_mogwai [7]

Answer:

1.7 miles.

Step-by-step explanation:      

We have been given that Mark runs back and forth on a football field for a total of 3000 yards.

Since we know that 1 mile equals to 1760 yards. To find the number of miles Mark ran we will divide 3000 yards by number of yards in one mile (1760).

\text{ Mark ran}=\frac{3000\text{ yards}}{1760\frac{\text{yards}}{\text{mile}}}

\text{ Mark ran}=\frac{3000\text{ yards}}{1760}\times \frac{\text{miles}}{\ext{yards}}

After cancelling out yards from numerator and denominator we will get,

\text{ Mark ran}=\frac{3000}{1760} \text { miles}}

\text{ Mark ran}=1.7045454545454545\text{ miles}}\approx 1.7\text { miles}}

Therefore, Mark ran 1.7 miles on the football field.
