Answer:


79(1)/(3)\ (feet)/(second)

Explanation:

we know that


1\ hour=3,600\ seconds

To convert hour to seconds multiply by 3,600


1\ mile=5,280\ feet

To convert miles to feet multiply by 5,280

In this problem we have


50\ (miles)/(hour)

Convert to ft/sec

so


50\ (miles)/(hour)=50((5,280)/(3,600))=(264,000)/(3,600)\ (feet)/(second)

Simplify


(220)/(3)\ (feet)/(second)

Convert to mixed number


(220)/(3)\ (feet)/(second)=(219)/(3)+(1)/(3)=79(1)/(3)\ (feet)/(second)
