Question

If you are traveling at a speed of

50
miles per hour, how many feet per second is this? Show your work using units and Giant Ones.

Answer 1

`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)`
